In 2023, it was decided to use the distict ASR systems that we already had in Icelandic to automatically verify as much data as possible. The verification process consited in transcribing the recordings using various ASR systems. If one or more of them get a transcription that perfectly matches the reference transcription, the recording is considered as verified. * The resulting corpus of more than 1 million recordings is too big to download it all at once. In consequence, it was decided to split it in 7 portions with the hope that it will be more manageable this way. ### Source Data #### Initial Data Collection and Normalization * The utterances were recorded by a smartphone or the web app. * The data was collected using the website https://samromur.is, code of which is available at https://github.com/cadia-lvl/samromur. * Each recording contains one read sentence from a script. ### Annotations #### Annotation process Prompts were pulled from these corpora if they met the criteria of having only letters which are present in the Icelandic alphabet, and if they are listed in the [DIM: Database Icelandic Morphology](https://aclanthology.org/W19-6116.pdf). There are also synthesised prompts consisting of a name followed by a question or a demand, in order to simulate a dialogue with a smart-device. #### Who are the annotators? The audio files content was automatically verified using ASR systems such as: [Wav2Vec2](https://huggingface.co/carlosdanielhernandezmena/wav2vec2-large-xlsr-53-icelandic-ep10-1000h), [Whisper](https://huggingface.co/language-and-voice-lab/whisper-large-icelandic-30k-steps-1000h), [Faster-Whisper](https://huggingface.co/language-and-voice-lab/whisper-large-icelandic-30k-steps-1000h-ct2) and [NeMo](https://huggingface.co/carlosdanielhernandezmena/stt_is_quartznet15x5_ft_ep56_875h). If any of the ASR systems gets a transcript that perfectly matches the reference transcription, the speech-recording is then cosidered as verified. ### Personal and Sensitive Information The dataset consists of people who have donated their voice. You agree to not attempt to determine the identity of speakers in this dataset. ## Considerations for Using the Data ### Social Impact of Dataset This contribution describes a project of speech data collection, using the web application [Samrómur](samromur.is) which is built upon [Common Voice](https://commonvoice.mozilla.org/), Mozilla Foundation's web platform for open-source voice collection. The goal of the project is to build a large-scale speech corpus for Automatic Speech Recognition (ASR) for Icelandic. Samrómur is the largest open speech corpus for Icelandic collected from the public domain. ### Discussion of Biases * The participants are aged between 4 to 90 years old. The speech files were recorded by a smartphone or the web app. * Participants self-reported their age group, gender, and the native language. * The corpus contains 1,002,157 from 16,729 speakers, totalling 967 hours and 7 minutes. * The number of recordings coming from female speakers are 714,564, totalling 697h22m. * The number of recordings coming from male speakers are 282,499, totalling 264h28m. * The number of recordings where the gender, the age or both is unknown are 5,094, totalling 5h16m. These recordings belong to the split called "other". ### Other Known Limitations "Samrómur Milljón" by the Language and Voice Laboratory (LVL) from Reykjavik University (RU) is licensed under a Creative Commons Attribution 4.0 International (CC BY 4.0) License with the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. ## Additional Information ### Dataset Curators The corpus was curated by [Carlos Daniel Hernández Mena](https://huggingface.co/carlosdanielhernandezmena) during 2023 at the [Language and Voice Laboratory](https://lvl.ru.is/) from [Reykjavik University](https://en.ru.is/). ### Licensing Information [CC-BY-4.0](https://creativecommons.org/licenses/by/4.0/) ### Citation Information ``` @misc{menasamromurmilljon2023, title={Samrómur Milljón, Audio and Transcriptions}, author={Hernández Mena, Carlos Daniel and Guðnason, Jón}, publisher={Reykjavík University} year={2023}, url={https://huggingface.co/datasets/language-and-voice-lab/samromur_milljon}, } ``` ### Contributions This project was funded by the Language Technology Programme for Icelandic 2019-2023.
