Soniox TTS Now Available for Telnyx Voice AI

Telnyx added Soniox text-to-speech to its Voice AI catalog, offering about 200 voices that each speak 60 languages from a single model. Developers address the voices as `Soniox.tts-rt-v2.<Name>` — including `Soniox.tts-rt-v2.Adrian`, `Soniox.tts-rt-v2.Emma`, and `Soniox.tts-rt-v2.Nina` — and can set `language` to a two-letter ISO 639-1 code with `en` as the default. The voices work over `POST /v2/text-to-speech/speech`, WebSocket streaming, Call Control `speak`, `gather_using_speak`, and conference `<Say>`, with `pcm_mulaw` and `pcm_alaw` output, `speed` from `0.7` to `1.3`, and a `reduce_silence` option.
