Edge0 releases 0.6B voice cloning TTS model Audio8-TTS-Realistic

On October 30, 2026, Edge0 released the open-source-weight voice cloning TTS model Audio8-TTS-Realistic. According to a MarkTechPost report, the model has 601M parameters, supports 23 languages, and its weights and code are released under Apache 2.0. The model requires only one reference audio clip and its corresponding text to perform zero-shot voice cloning, and can also generate speech directly when no reference voice is available. Self-reported results show that its average error rate on the CV3 nine-language benchmark is 4.86%, lower than Qwen3-TTS-1.7B's 7.73%; however, on the MiniMax benchmark it lags behind 4B-class models, with Thai WER reaching 48.57%. There are currently no further developments.

AssemblyAI launches its first text-to-speech model, AssemblyAI-TTS-1

On October 29, 2026, AssemblyAI launched its first text-to-speech model, AssemblyAI-TTS-1, and made it generally available, targeting real-time telephony voice agents, priced at $15 per 1 million characters, with no annual contract and no concurrency tiers. According to a MarkTechPost report, the model is offered only as a hosted API in us-east-1 and eu-north-1, supports HTTP, WebSocket and OpenAI-compatible interfaces, and includes more than 4,000 voices, instant voice cloning and 6 languages; vendor self-testing shows 93.7% entity accuracy and a median time to first byte of 47 milliseconds, but Cekura's independent benchmark measured a streaming latency of 159 milliseconds and a reading accuracy of 81.5%, and at launch it did not yet support SSML, speaking-rate control or emotion tags. On the same day, Artificial Analysis' Provider Voice Arena evaluation showed AssemblyAI-TTS-1 ranked 12th with an Elo of 1227, ranked 16th with a pronunciation robustness score of 81.7%, and generated at 162 characters per second. Later that day, OpenRouter announced that AssemblyAI-TTS-1 was live, targeting voice agent scenarios, with service available from US or EU nodes.
