| ## Dataset Description |
|
|
| AISHELL-3 is a large-scale and high-fidelity multi-speaker Mandarin speech corpus published by Beijing Shell Shell Technology Co., Ltd. |
|
|
| The dataset is designed for training multi-speaker Text-to-Speech (TTS) systems. It contains roughly **85 hours** of emotion-neutral recordings spoken by **218 native Mandarin Chinese speakers**, with a total of **88,035 utterances**. |
|
|
| Auxiliary speaker attributes, including **gender**, **age group**, and **native accents**, are explicitly marked and provided in the corpus. |
|
|
| Transcripts are provided at both: |
|
|
| - Chinese character level |
| - Pinyin level |
|
|
| The word and tone transcription accuracy rate is above **98%**, based on professional speech annotation and strict quality inspection for tone and prosody. |
