Y cyntaf yw enw’r ffeil sain. Y trawsgrifiad Cymraeg sydd yn yr ail golofn. Y cyfieithiad Saesneg sydd yn yr olaf. Dyma'r wybodaeth am y colofnau. | Maes| Esboniad | | ------ | ------ | | `mp3_filename`| Enw'r ffeil sain o fewn y ffolder 'clips'| | `Original` | Y trawsgrifiad Cymraeg| | `Translation` | Y cyfieithiad Saesneg| ## Y Broses o Greu’r Adnodd Casglwyd y ffeiliau sain yn bennaf o bodlediadau Cymraeg gyda chaniatâd eu perchnogion yn ogystal â'r cyfranwyr unigol. Rydym yn ddiolchgar tu hwnt i’r bobl yna. Yn ogystal, crewyd rhywfaint o sgriptiau ar batrwm eitemau newyddion ac erthyglau a'u darllen gan ymchwilwyr yr Uned Technolegau Iaith er mwyn sicrhau bod cynnwys o'r math hwnnw yn y banc. Gyrrwyd y ffeiliau sain trwy ein trawsgrifiwr awtomataidd mewnol i segmentu’r sain a chreu trawsgrifiadau amrwd. Defnyddiwyd pecyn trawsgrifio Elan 6.4 (ar gael o https://archive.mpi.nl/tla/elan) gan drawsgrifwyr profiadol i wrando ar a chywiro’r trawsgrifiad amrwd. ## Nodyn Ynghylch Anonymeiddio’r Cynnwys Er tegwch i’r cyfranwyr, rydyn ni wedi anonymeiddio’r trawsgrifiadau. Penderfynwyd anonymeiddio nid yn unig enwau pobl unigol, ond hefyd unrhyw Wybodaeth Bersonol Adnabyddadwy (PII) gan gynnwys, ond nid yn gyfunedig i: * Rhif ffôn * Teitlau swyddi/galwedigaethau * Gweithleoedd * Enwau mannau cyhoeddus * Lleoliad daearyddol * Dyddiadau/amseroedd Wrth drawsgrifio marciwyd pob segment oedd yn cynnwys PII gyda’r tag \, yna wnaethom hidlo allan pob segment oedd yn cynnwys tag \ er mwyn sicrhau nad oedd unrhyw wybodaeth bersonol yn cael eu cyhoeddi fel rhan o’r adnodd hwn. Rydym hefyd wedi newid trefn trawsgrifiadau i fod ar hap, felly nid ydynt wedi'u cyhoeddi yn y drefn y maent yn eu ymddangos yn y ffeiliau sain gwreiddiol. ## Confensiynau Trawsgrifio Datblygwyd y confensiynau trawsgrifio hyn er mwyn sicrhau fod y trawsgrifiadau nid yn unig yn verbatim ond hefyd yn gyson. Fe’u datblygwyd trwy gyfeirio at gonfensiynau a ddefnyddir gan yr Uned yn y gorffennol, confensiynau eraill megis y rhai a defnyddiwyd yng nghorpora CorCenCC, Siarad, CIG1 a CIG2, a hefyd trwy broses o ddatblygu parhaol wrth i’r tîm ymgymryd â’r dasg o drawsgrifio. **NODWCH** - gan ein bod wedi datblygu’r egwyddorion trawsgrifio yn rhannol wrth ymgymryd â’r dasg o drawsgrifio nid yw’r trawsgrifiadau cynnar o reidrwydd yn dilyn yr egwyddorion cant y cant. Bwriadwn wirio’r trawsgrifiadau wedi i ni fireinio’r confensiynau. ### Collnodau Ni ddefnyddiwyd collnodau i marcio pob un llythyren a hepgorwyd gan siaradwyr. Er enghraifft, _gwitho_ (sef ynganiad o _gweithio_) sy’n gywir, nid _gw’ith’o_ Yn hytrach, defnyddiwyd collnodau i wahaniaethu rhwng gwahanol eiriau oedd yn cael eu sillafu'r union yr un fath fel arall. Er enghraifft rydym yn defnyddio collnod o flaen _’ma_ (sef _yma_) i wahaniaethu rhyngddo â _ma’_ (sef _mae_), _gor’o’_ i wahaniaethu rhwng _gorfod_ a ffurf trydydd person unigol amser dibynnol presennol _gori_, a _pwysa’_ i wahaniaethu rhwng ffurf luosog _pwys_ a nifer o ffurfiau berfol posib _pwyso_. Fodd bynnag, ceir eithriad i’r rheol hon, a hynny pan fo sillafu gair heb gollnod yn newid sŵn y llythyren cyn neu ar ôl y collnod, ac felly _Cymra’g_ sy’n gywir, nid _Cymrag_. ### Tagiau Wrth drawsgrifio, defnyddiwyd y tagiau hyn i recordio elfennau oedd y tu hwnt i leferydd yr unigolion: * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ Rhagwelwn y bydd y rhestr hon yn chwyddo wrth i ni drawsgrifio mwy o leferydd ac wrth i ni daro ar draws mwy o elfennau sydd y tu hwnt i leferydd unigolion. ### Synau nad ydynt yn eiriol Ymdrechwyd i drawsgrifio synau nad ydynt yn eiriol yn gyson. Er enghraifft, defnyddiwyd _yy_ bob tro (yn hytrach nag _yrr_, _yr_ neu _err_ neu gymysgedd o’r rheiny) i gynrychioli neu adlewyrchu’r sŵn a wnaethpwyd pan oedd siaradwr yn ceisio meddwl neu oedi wrth siarad. Defnyddiwyd y canlynol wrth drawsgrifio: * yy * yym * hmm * m-hm Eto, rhagwelwn y bydd y rhestr hon yn chwyddo wrth i ni drawsgrifio mwy o leferydd ac wrth i ni daro ar draws mwy o synau nad ydynt yn eiriol. ### Geiriau Saesneg Rydym wedi amgylchynu bob gair neu ymadrodd Saesneg gyda sêr, er enghraifft: > Dwi’n deall **\*sort of\***. ### Cymreigio berfenwau Pan fo siaradwyr yn defnyddio geiriau Saesneg fel berfenwau (trwy ychwanegu _io_ ar ddiwedd y gair er enghraifft) rydym wedi ymdrechu i sillafu’r gair gan ddefnyddio confensiynau sillafu Cymreig yn hytrach nag ychwanegu _io_ at sillafiad Saesneg o’r gair. Er enghraifft rydym wedi trawsgrifio _heitio_ yn hytrach na _hateio_, a _lyfio_ yn hytrach na _loveio_. ### Cywiro cam-siarad I sicrhau ein bod ni’n glynu at egwyddorion trawsgrifio verbatim penderfynwyd na ddylem gywiro cam-siarad neu gam-ynganu siaradwyr. Er enghraifft, yn y frawddeg ganlynol: > enfawr fel y diffyg o fwyd yym **efallu** cam-drin mae'n amlwg mai’r gair _efallai_ sydd dan sylw mewn gwirionedd, ond fe’i trawsgrifiwyd fel ei glywir. ### Atalnodi Defnyddiwyd atalnodau llawn, marciau cwestiwn ac ebychnodau wrth drawsgrifio’r lleferydd. Rydym wedi amgylchynu bob gair neu ymadrodd sydd wedi ei dyfynnu gyda _”_, er enghraifft: > Dywedodd hi **”Dwi’n mynd”** ond aeth hi ddim. ### Nodyn ynghylch ein defnydd o gomas Gan mai confensiwn ysgrifenedig yw coma yn y bôn, ni ddefnyddiwyd comas cymaint wrth drawsgrifio. Byddai defnyddio coma lle y disgwylir i’w weld mewn testun ysgrifenedig ddim o reidrwydd wedi adlewyrchu lleferydd yr unigolyn. Dylid cadw hynny mewn cof wrth ddarllen y trawsgrifiadau. ### Sillafu llythrennau Sillafwyd llythrennau unigol yn hytrach na thrawsgrifio’r llythrennau unigol yn unig. Hynny yw, hyn sy’n gywir: > Roedd ganddo **ow si di** **ac nid:** > Roedd ganddo **O C D** **na chwaith:** > Roedd ganddo **OCD** ### Rhifau Trawsgrifiwyd rhifau fel geiriau yn hytrach na digidau, hynny yw hyn sy’n gywir: > Y flwyddyn dwy fil ac ugain **ac nid:** > Y flwyddyn 2020 ### Gorffen gair ar ei hanner Marciwyd gair oedd wedi ei orffen ar ei hanner gyda `-`. Er enghraifft: > Ma’n rhaid i mi **ca-** cael diod. ### Gorffen brawddeg ar ei hanner/ailddechrau brawddeg Marciwyd brawddeg oedd wedi ei gorffen ar ei hanner gyda `...`. Er enghraifft: > Ma’n rhaid i mi ca’l... Ma’ rhaid i mi brynu diod. ### Siaradwr yn torri ar draws siaradwr arall Ceir yn y data llawer o enghreifftiau o siaradwr yn torri ar draws y prif leferydd gan ddefnyddio synau nad ydynt yn eiriol, geiriau neu ymadroddion (megis _m-hm_, _ie_, _ydi_, _yn union_ ac ati). Pan oedd y ddau siaradwr i'w clywed yn glir ag ar wahân, rhoddwyd `...` ar ddiwedd rhan gyntaf y lleferydd toredig, a `...` arall ar ddechrau ail ran y lleferydd toredig, fel yn yr enghraifft ganlynol: > Ond y peth yw... M-hm. ...mae’r ddau yn wir Pan nad oedd y ddau siaradwyr i'w clywed yn glir ag ar wahân, fe hepgorwyd y lleferydd o’r data. ### Rhegfeydd Dylid nodi ein bod ni heb hepgor rhegfeydd wrth drawsgrifio. ## Y Dyfodol Wrth ddefnyddio’r banc trawsgrifiadau dylid cadw mewn cof mai fersiwn cychwynnol ydyw. Bwriadwn fireinio a chysoni ein trawsgrifiadau ymhellach, ac ychwanegu mwy fyth o drawsgrifiadau i’r banc yn rheolaidd dros y flwyddyn nesaf ## Cyfyngiadau Er mwyn parchu'r cyfrannwyr, wrth lwytho'r data hwn i lawr rydych yn cytuno i beidio â cheisio adnabod y siaradwyr yn y data. ## Diolchiadau Diolchwn i'r cyfrannwyr am eu caniatâd i ddefnyddio'u lleferydd. Rydym hefyd yn ddiolchgar i Lywodraeth Cymru am ariannu’r gwaith hwn fel rhan o broject Technoleg Testun, Lleferydd a Chyfieithu ar gyfer yr Iaith Gymraeg. --- # Bangor Transcription Bank This resource is a bank of 40 hours of segments of natural speech from over 50 contributors in mp3 file format, together with corresponding 'verbatim' transcripts of the speech in .tsv file format. The majority of the speech is spontaneous, natural speech. We distribute this material under a CC0 open license. ## Purpose The purpose of these transcripts is to act as training data for speech recognition models, including [our wav2vec models](https://github.com/techiaith/docker-wav2vec2-cy). For that purpose, transcriptions are more verbatim than what is seen in traditional transcriptions and than what is required for subtitling purposes, thus a bespoke set of conventions has been developed for the transcription work ([see below](#transcription_conventions) ). Our wav2vec models use an auxiliary component, namely a 'language model', to further standardize the speech recognition model’s output in order that it be more similar to traditional transcriptions and subtitles. We have provided 3 .tsv files, namely clips.tsv, train.tsv and test.tsv. clips.tsv contains all of our transcripts. train.tsv and test.tsv were created to provide 'standard' sets that allow users to compare models trained by different trainers fairly, i.e. they were created as a 'benchmark'. train.tsv contains 80% of our transcripts, and test.tsv contains the remaining 20%. Here is an example of the data content: ``` audio_filename audio_filesize transcript duration f86a046fd0964e0386d8c1363907183d.mp3 898272 *post industrial* yym a gyda yy dwi'n ca'l deud 5092 f0c2310fdca34faaa83beca5fa7ed212.mp3 809720 sut i ymdopio felly, wedyn erbyn hyn mae o nôl yn y cartra 4590 3eec3feefe254c9790739c22dd63c089.mp3 1335392 Felly ma' hon hefyd yn ddogfen fydd yn trosglwyddo gyda'r plant bobol ifanc o un cam i'r llall ac hefyd erbyn hyn i'r coleg 'lly. 7570 ``` There are four columns in the .tsv files. The first is the name of the audio file. The second is the size of the audio file. The transcript itself appears in the third column. The length of the audio clip appears in the last. Here is the information about the columns. | Field| Explanation | | ------ | ------ | | `audio_filename`| The name of the audio file within the 'clips' folder| | `audio_filesize` | The size of the file | | `transcript` | Transcript | | `duration` | Duration of the clip in milliseconds. | ### Translation of a Sub-set We have also translated 500 of our transcripts into English and published the translations together with their original transcripts in the translations.tsv file. Here is an example of the data content: ``` mp3_filename Original Translation 8d6b7347cae6092930aa9b436045e33d.mp3 fel oedden ni odd yym odd pob pennod yn troi mewn i Ben-Hur rywfaint ag yn yy, odd hi'n eitha anodd as we were um every episode turned into Ben-Hur, somewhat, and was er, it was quite difficult ce526eaf61557b8e3eb53eb1a2f55076.mp3 pan ddechreuon ni'r podlediad yma y bwriad odd i ga'l un pennod bob bythefnos ond yy, wrth i ni fynd ymlaen when we started this podcast the intention was to have one episode every two weeks but er, as we go on ``` There are three columns in the translation.tsv file. The first is the name of the audio file. The Welsh transcription is in the second column. The English translation is in the last. Here is the information about the columns. | Field| Explanation | | ------ | ------ | | `mp3_filename`| The name of the audio file within the 'clips' folder| | `Original` | The Welsh transcription| | `Translation` | The English translation| ## The Process of Creating the Resource The audio files were mainly collected from Welsh podcasts, after having gained the consent of the podcast owners and individual contributors to do so. We are extremely grateful to those people. In addition, some scripts were created which mimicked the pattern of news items and articles. These scripts were then read by Language Technologies Unit researchers in order to ensure that content of that type was included in the bank. The audio files were run through our in-house automated transcriber to segment the audio and create raw transcripts. Using Elan 6.4 (available from https://archive.mpi.nl/tla/elan), experienced transcribers listened to and corrected the raw transcript. ## A Note About Content Anonymization Out of respect to the contributors, we have anonymised all transcripts. It was decided to anonymize not only the names of individual people, but also any other Personally Identifiable Information (PII) including, but not limited to: * Phone number * Job titles/occupations * Workplaces * Names of public places * Geographical location * Dates/times When transcribing, all segments containing PII were marked with the \ tag, we then filtered out all segments containing a \ tag to ensure no personal information was published as part of this resource. We have also randomized the order of the segments so that they are not published in the order they appeared in the original audio files. ## Transcription Conventions These transcription conventions were developed to ensure that the transcriptions were not only verbatim but also consistent. They were developed by referring to conventions used by the Unit in the past, conventions such as those used in the CorCenCC, Siarad, CIG1 and CIG2 corpora, and also through a process of ongoing development as the team undertook the task of transcription. **NOTE** - as we have partially developed the conventions at the same time as undertaking the task of transcription the early transcriptions may not follow the latest principles faithfully. We intend to check the transcripts after we have refined the conventions. ### Apostrophes Apostrophes were not used to mark every single letter omitted by speakers. For example, _gwitho_ (which is a pronunciation of _gweithio_) is correct, not _gw’ith'o_. Rather, apostrophes were used to distinguish between different words that were otherwise spelled identically. For example we use an apostrophe in front of _'ma_ (a pronunciation of _yma_) to distinguish it from _ma'_ (a pronunciation of _mae_), _gor'o'_ to distinguish between _gorfod_ and the third person singular form of the present dependent tense _gori_, and _pwysa'_ to distinguish between the plural form of _pwys_ and a number of possible verb forms of _pwyso_. However, there is an exception to this rule, that being when spelling a word without an apostrophe would change the sound of the letter before or after the apostrophe, thus _Cymra'g_ is correct, not _Cymrag_. ### Tags When transcribing, these tags were used to record elements that were external to the speech of the individuals: * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ * \ We anticipate that this list will grow as we transcribe more speech and as we come across more elements that are external to the speech of individuals. ### Non-verbal sounds Efforts were made to transcribe non-verbal sounds consistently. For example, _yy_ was always used (rather than _yrr_, _yr_ or _err_, or a mixture of those) to represent or reflect the sound made when a speaker was trying to think or paused in speaking. The following were used in transcription: * yy * yym * hmm * m-hm Again, we anticipate that this list will grow as we transcribe more speech and as we encounter more non-verbal sounds. ### English words We have surrounded each English word or phrase with asterixis, for example: > Dwi’n deall **\*sort of\***. ### Adapting English words as Welsh language infinitives When speakers use English words as infinitives (by adding _io_ at the end of the word for example) we have endeavoured to spell the word using Welsh spelling conventions rather than adding _io_ to the English spelling of the word. For example we have transcribed _heitio_ instead of _hateio_, and _lyfio_ instead of _loveio_. ### Correction of mis-pronunciations To ensure that we adhere to the principles of verbatim transcription it was decided that we should not correct speakers' mis-pronunciations. For example, in the following sentence: > enfawr fel y diffyg o fwyd yym **efallu** cam-drin it is clear that _efallai_ is the intended word, but it is transcribed as it is heard. ### Punctuation Full stops, question marks and exclamation marks were used when transcribing the speech. We have surrounded all quoted words or phrases with _”_, for example: > Dywedodd hi **”Dwi’n mynd”** ond aeth hi ddim. ### A note about our use of commas As a comma is essentially a convention used for written text, commas were not used prolifically in transcription. Using a comma where one would expected to see it in a written text during transcription would not necessarily have reflected the individual's speech. This should be borne in mind when reading the transcripts. ### Individual letters Individual letters were spelled out rather than being transcribed as individual letters. That is, this is correct: > Roedd ganddo **ow si di** **not:** > Roedd ganddo **O C D** **nor:** > Roedd ganddo **OCD** ### Numbers Numbers were transcribed as words rather than digits, thus this is correct: > Y flwyddyn dwy fil ac ugain **rather than:** > Y flwyddyn 2020 ### Half-finished words Half-finished words are marked with a `-`. For example: > Ma’n rhaid i mi **ca-** cael diod. ### Half-finished/restarted sentences Half-finished sentences are marked with a `...`. For example: > Ma’n rhaid i mi ca’l... Ma’ rhaid i mi brynu diod. ### Speaker interruptions There are many examples of a speaker interrupting another speaker by using non-verbal sounds, words or phrases (such as _m-hm_, _ie_, _ydi_, _yn union_ etc.) in the data. When the two speakers could be heard clearly and distinctly, a `...` was placed at the end of the first part of the broken speech, and another `...` at the beginning of the second part of the broken speech, as in the following example: > Ond y peth yw... M-hm. ...mae’r ddau yn wir When the two speakers could not be heard clearly and distinctly, the speech was omitted from the data. ### Swearwords It should be noted that we have not omitted swearwords when transcribing. ## The future That this is an initial version of the transcript bank should be borne in mind when using this resource. We intend to refine and harmonize our transcripts further, and add yet more transcripts to the bank regularly over the next year. ## Restrictions In order to respect the contributors, by downloading this data you agree not to attempt to identify the speakers in the data. ## Acknowledgements We thank the contributors for their permission to use their speech. We are also grateful to the Welsh Government for funding this work as part of the Text, Speech and Translation Technology project for the Welsh Language.
