Description

Speechify provides a range of Simba models within its text-to-speech API, designed for real-time voice generation in English and various European languages, as well as for a wide array of multilingual applications. For new English integrations, Simba 3.2 is the recommended choice, featuring streaming-native synthesis, minimized time to first byte, enhanced expressivity compared to prior versions, and comprehensive support for SSML and emotional modulation. Meanwhile, Simba 3.0 offers streaming-native speech capabilities in English, German, Spanish, French, Italian, and Brazilian Portuguese, with language selection managed via the request or voice locale. Simba Multilingual expands support to 35 locales across 30 languages, accommodating mixed-language content and incorporating automatic language detection, while the legacy Simba English model remains available for those requiring compatibility. Developers can easily select their preferred model using a single parameter, allowing for seamless switching without altering other request components, such as voice, format, and SSML configurations. This flexibility ensures that developers can optimize their integration to best meet their specific needs.
