# *Dolly-Audio: Vietnamese Multi-Speaker High-Quality Speech Corpus*

## *Dataset Summary*

*Dolly-Audio* is a large-scale, high-quality Vietnamese speech corpus created by the *Dolly AI Team*.
Inspired by Dolly, the world’s first cloned mammal, the project aims to advance research in Vietnamese speech synthesis, speech recognition, and voice modeling.

This release provides nearly *1,000 hours of professionally cleaned audio*, featuring *152 speakers* across different Vietnamese regions and speaking styles. Text transcripts span a wide variety of domains to ensure linguistic diversity and model robustness.

---

## *Key Features*

* ~1,000 hours of high-quality Vietnamese speech
* 152 multi-region speakers with diverse accents
* Cleaned, noise-free audio; no background music
* Sentence-level boundary trimming for natural prosody
* Rich transcript domains (news, entertainment, education, conversational, etc.)
* Estimated *near-zero WER (≈ 0%)* from manual sampling
* Suitable for TTS, ASR, voice cloning, and speech research

---

## *Intended Use*

The dataset is ideal for:

* Multi-speaker text-to-speech (TTS)
* Automatic speech recognition (ASR)
* Voice cloning and speaker adaptation
* Prosody modeling
* Linguistic and phonetic research

Commercial use is *not permitted* under the license.
