About
Simba 3.5 is Speechify's streaming text-to-speech model and the recommended model on the SpeechifyAI developer API since October 18, 2026, with its priced launch on October 21. One model ID (simba-3.5) speaks 48 languages, and every catalog voice, including a workspace's own zero-shot clones, speaks each of them; the language parameter selects the language per request. It supports SSML pauses, rate, pitch, volume and pronunciation over REST and WebSocket streaming. Speechify reports 72 ms time to first audio for 95% of streaming requests. List price is $15 per 1M characters on Starter, $12 on Pro and $10 on Scale.
