title: SPEECH-COCO

description: <strong>SpeechCoco</strong> <em>Introduction</em> Our corpus is an extension of the MS COCO image recognition and captioning dataset. MS COCO comprises images paired with a set of five captions. Yet, it does not include any speech. Therefore, we used Voxygen's text-to-speech system to synthesise the available captions. The addition of speech as a new modality enables MSCOCO to be used for researches in the field of language acquisition, unsupervised term discovery, keyword spotting, or semantic embedding using speech and vision. Our corpus is licensed under a Creative Commons Attribution 4.0 License. <em>Data Set</em> This corpus contains <strong>616,767</strong> spoken captions from MSCOCO's val2014 and train2014 subsets (respectively 414,113 for train2014 and 202,654 for val2014). We used 8 different voices. 4 of them have a British accent (Paul, Bronwen, Judith, and Elizabeth) and the 4 others have an American accent (Phil, Bruce, Amanda, Jenny). In order to make the captions sound more natural, we used SOX <em>tempo</em> command, enabling us to change the speed without changing the pitch. 1/3 of the captions are 10% slower than the original pace, 1/3 are 10% faster. The last third of the captions was kept untouched. We also modified approximately 30% of the original captions and added <strong>disfluencies</strong> such as "um", "uh", "er" so that the captions would sound more natural. Each WAV file is paired with a JSON file containing various information: timecode of each word in the caption, name of the speaker, name of the WAV file, etc. The JSON files have the following data structure: <pre><code class="language-json">{ "duration": float, "speaker": string, "synthesisedCaption": string, "timecode": list, "speed": float, "wavFilename": string, "captionID": int, "imgID": int, "disfluency": list }</code></pre> On average, each caption comprises 10.79 tokens, disfluencies included. The WAV files are on average 3.52 seconds long. <em>Repository</em> The repository is organized as follows: CORPUS-MSCOCO (~75GB once decompressed) <strong>train2014/</strong> : folder contains 413,915 captions json/ wav/ translations/ train_en_ja.txt train_translate.sqlite3 train_2014.sqlite3 <strong>val2014/</strong> : folder contains 202,520 captions json/ wav/ translations/ train_en_ja.txt train_translate.sqlite3 val_2014.sqlite3 <strong>speechcoco_API/</strong> speechcoco/ __init__.py speechcoco.py setup.py <em>Filenames</em> <strong>.wav</strong> files contain the spoken version of a caption <strong>.json</strong> files contain all the metadata of a given WAV file <strong>.sqlite3</strong> files are SQLite databases containing all the information contained in the JSON files We adopted the following naming convention for both the WAV and JSON files: <em>imageID_captionID_Speaker_DisfluencyPosition_Speed[.wav/.json]</em> <em>Script</em> We created a script called <strong>speechcoco.py</strong> in order to handle the metadata and allow the user to easily find captions according to specific filters. The script uses the *.db files. Features: <strong>Aggregate all the information in the JSON files into a single SQLite database</strong> <strong>Find captions according to specific filters (name, gender and nationality of the speaker, disfluency position, speed, duration, and words in the caption).</strong> <em>The script automatically builds the SQLite query. The user can also provide his own SQLite query.</em> <em>The following Python code returns all the captions spoken by a male with an American accent for which the speed was slowed down by 10% and that contain "keys" at any position</em> <pre><code class="language-python"># create SpeechCoco object db = SpeechCoco(train_2014.sqlite3, train_translate.sqlite3, verbose=True) # filter captions (returns Caption Objects) captions = db.filterCaptions(gender="Male", nationality="US", speed=0.9, text='%keys%') for caption in captions: print('\n{}\t{}\t{}\t{}\t{}\t{}\t\t{}'.format(caption.imageID, caption.captionID, caption.speaker.name, caption.speaker.nationality, caption.speed, caption.filename, caption.text))</code></pre> <pre><code>... 298817 26763 Phil 0.9 298817_26763_Phil_None_0-9.wav A group of turkeys with bushes in the background. 108505 147972 Phil 0.9 108505_147972_Phil_Middle_0-9.wav Person using a, um, slider cell phone with blue backlit keys. 258289 154380 Bruce 0.9 258289_154380_Bruce_None_0-9.wav Some donkeys and sheep are in their green pens . 545312 201303 Phil 0.9 545312_201303_Phil_None_0-9.wav A man walking next to a couple of donkeys. ...</code></pre> <strong>Find all the captions belonging to a specific image</strong> <pre><code class="language-python">captions = db.getImgCaptions(298817) for caption in captions: print('\n{}'.format(caption.text))</code></pre> <pre><code>Birds wondering through grassy ground next to bushes.
