loudkit

Twenty voices across ten languages, from loudreader/loudr-1, running the loudkit engine on ZeroGPU.

Two tabs

• Voices. Twenty voices, each beside the reference recording it was enrolled from. English first, with a dropdown for the other nine languages. The samples were rendered ahead of time and ship in this repo, so playing them uses no GPU. Under them is a box for your own text, up to 1,000 characters.
• Clone. A voice from about ten seconds of audio. Try a shipped example, or record yourself.

ZeroGPU bills GPU time to the visitor, not to the owner. An anonymous visitor gets about two minutes a day. A signed-in free account gets about five. Listening costs none of it.

Cloning and consent

Clone your own voice, or a voice you have permission to use.

• Four shipped examples let you hear cloning without recording anything. Their donors released them for building TTS voices.
• Recording yourself is the next path. It clears the example.
• An upload is last, and needs an explicit confirmation.
• Recordings are deleted when the request ends. The voice embeddings are never written to disk and never leave the process.
• Cloned audio carries no download button.

See RESPONSIBLE_USE.

Determinism

The Voices tab has a determinism check. It renders the same text twice at the same seed and prints the SHA-256 of both waveforms. They match.

That holds within this build and this device. loudkit promises a bit-identical waveform for the same seed, build, backend and input. It does not promise that your machine matches this GPU. See the identity contract.

Run it locally

pip install "loudkit[torch,audio,enroll,hub]"

import loudkit as lk

engine = lk.load("loudreader/loudr-1")
voice = lk.voice("kathleen", repo="loudreader/loudr-1")
engine.synthesize_long("Hello from loudkit.", voice, seed=7).save("hello.wav")

Audio in this Space, and from Result.save, carries C2PA provenance: the algorithm fingerprint, the recipe and the seed.

Voice sources

Every voice is enrolled from a public-domain or openly licensed recording. voices.json in this repo carries the full record for each one: donor, source, licence, consent, and the SHA-256 of both the reference and the sample.
