Overview

Audio8-TTS-Realistic-Air is Edge0’s 0.6B multilingual text-to-speech model for speech generation with or without a reference voice. It supports zero-shot voice cloning from reference audio and its exact transcript, and lists 23 supported languages. Maintained by Edge0.

Best use cases

Generate speech from text in the 23 listed languages, or clone a voice using a clean reference recording and matching transcript. It can also be deployed through an SGLang Omni adapter with an OpenAI-compatible speech API.

Limitations

Language quality varies. Reported error-rate and speaker-similarity metrics assess intelligibility and similarity, not perceived realism; the supplied evaluation does not directly quantify realism. Runtime checks were performed on an NVIDIA H20 in BF16, but throughput and streaming were not benchmarked.…
