Australian English Speech

An Australian accent speech dataset: 110 hours of Australian English audio with transcripts, from the Australian titles in the LibriVox catalogue, cut into short clips for text-to-speech, voice cloning and speech recognition.

Open English speech corpora are overwhelmingly American. This one is Australian, public domain, and free of any redistribution or model-release restrictions.

LibriVox recordings are released into the public domain, and the books themselves are public domain, so this dataset is unencumbered: train on it, redistribute it, ship models built from it.

How it was built

1. Australian titles taken from LibriVox's own catalogue search.
2. Each section downloaded from archive.org.
3. Gentle denoising with DeepFilterNet 3 (atten_lim_db=6). LibriVox audio is already clean, so this only shaves the hiss rather than reshaping the voice.
4. Silero VAD segmentation into 3-15 s clips that start and end on silence.
5. Transcription with faster-whisper large-v3-turbo.
6. Clips whose transcript is LibriVox boilerplate (the spoken intro and outro that top and tail every section) are dropped.

Things to know before you train on it

• Transcripts are machine-generated. Whisper is good but not perfect, and punctuation and capitalisation are inconsistent between clips. For anything where exact text matters, re-check against the public-domain source texts.
• Accent is not verified per reader. These are the Australian titles in the catalogue; LibriVox volunteers are international, so a minority of narrators reading Australian books are not themselves Australian. Filter by reader if you need a guaranteed accent.
• Per-reader volume is very uneven, from a few minutes to over ten hours. Balance or cap by reader if that matters for your training.
• Audio quality varies with the narrator's home recording setup, and some of the older recordings are effectively band-limited.

Credits

Every recording here was made by a LibriVox volunteer who donated it to the public domain. The narrators, and the books they read, are listed in CREDITS.md.
