Dataset Card for WenetSpeech4TTS

WenetSpeech4TTS is a multi-domain Mandarin corpus derived from the open-sourced WenetSpeech dataset. Tailored for the text-to-speech tasks, we refined WenetSpeech by adjusting segment boundaries, enhancing the audio quality, and eliminating speaker mixing within each segment. Following a more accurate transcription process and quality-based data filtering process, the obtained WenetSpeech4TTS corpus contains 12,800 hours of paired audio-text data. Furthermore, we have created subsets of varying sizes, categorized by segment quality scores to allow for TTS model training and finetuning.

VALL-E and NaturalSpeech 2 systems are trained and fine-tuned on these subsets, establishing benchmarks for the usability of WenetSpeech4TTS and the fair comparison of TTS systems. We make the corpus and corresponding benchmarks publicly available to advance research in this field. We provide audio-text pairs and DNSMOS P.808 scores for all audios in WenetSpeech4TTS. The checkpoints for VALL-E and NaturalSpeech 2 will be released soon.

Data format 

Audio file (.wav):
    Channels: 1
    Sample Rate: 16000
    Sample Encoding: 16-bit Signed Integer PCM

Each text file (.txt) includes the transcript corresponding to the speech and the timestamp of each word in the transcript.
    <Utt_id>\t<Text>\n
    \t<Timestamps>

The filelist of each set contains the relative paths of the wav and txt files for all metadata in the set.
    <Utt_id1>\t<wavpath1>\t<txtpath1>\n
    <Utt_id2>\t<wavpath2>\t<txtpath2>\n
    <Utt_id3>\t<wavpath3>\t<txtpath3>\n
    ...

The DNSMOS_lst of each set contains the DNSMOS P808 scores of all metadata in the set. We floor all scores to one decimal place.
    <Utt_id1>\t<score1>\n
    <Utt_id2>\t<score2>\n
    <Utt_id3>\t<score3>\n
    ...

You can directly download the .tar.gz file and the filelist, or use datasets.load() to access the dataset.

In our experiments, we used the SoX program to normalize the audio volume and found that it helped improve the synthesis quality, so we recommend researchers to perform volume normalization on the audio data and then use it to train the model.

Dataset Creation

Curation Rationale

WenetSpeech4TTS enhances the WenetSpeech dataset by improving audio quality and transcription accuracy to better serve TTS research and applications.

[More Information Needed]

Source Data

Sourced from YouTube and Podcasts, the original WenetSpeech data was meticulously processed to create WenetSpeech4TTS.

Data Collection and Processing

From WenetSpeech to WenetSpeech4TTS, we designed an automatic pipeline containing multiple processing steps. Specifically, we refined WenetSpeech for TTS by merging segments based on speaker similarity and pause duration, and by expanding segment boundaries to prevent truncated words. Audio quality was enhanced using the denoising model, followed by quality scoring. Furthermore, a speaker diarization system clustered segments from the same speaker, while a more advanced ASR system provided more accurate transcriptions.

Annotation process

We use the open-source industrial-level Paraformer-large system to obtain text transcriptions for the speech segments, this model achieved a 6.74% character error rate (CER) on the WenetSpeech “Test Net” set.
