Common Voice

Common Voice is a public domain speech corpus with 11.2K hours of read speech in 76 languages (the latest version 7.0). We provide examples for building Transformer models on this dataset.

Data preparation

Download and unpack Common Voice v4 to a path ${DATA_ROOT}/${LANG_ID}. Create splits and generate audio manifests with

python -m examples.speech_synthesis.preprocessing.get_common_voice_audio_manifest \
  --data-root ${DATA_ROOT} \
  --lang ${LANG_ID} \
  --output-manifest-root ${AUDIO_MANIFEST_ROOT} --convert-to-wav

Then, extract log-Mel spectrograms, generate feature manifest and create data configuration YAML with

python -m examples.speech_synthesis.preprocessing.get_feature_manifest \
  --audio-manifest-root ${AUDIO_MANIFEST_ROOT} \
  --output-root ${FEATURE_MANIFEST_ROOT} \
  --ipa-vocab --lang ${LANG_ID}

where we use phoneme inputs (--ipa-vocab) as example.

To denoise audio and trim leading/trailing silence using signal processing based VAD, run

for SPLIT in dev test train; do
    python -m examples.speech_synthesis.preprocessing.denoise_and_vad_audio \
      --audio-manifest ${AUDIO_MANIFEST_ROOT}/${SPLIT}.audio.tsv \
      --output-dir ${PROCESSED_DATA_ROOT} \
      --denoise --vad --vad-agg-level 2
done
