What

Soniox

Does

Soniox processes audio through a robust pipeline: first, its proprietary speech-to-text (STT) engine transcribes spoken language into text with high accuracy and low latency. The transcribed text can then be processed by large language models (LLMs) for understanding, summarization, or intent extraction, and optionally converted back to speech using TTS for conversational interfaces.

Developers typically build:

- Real-time transcription services

- Voice analytics dashboards

- Conversational AI agents

- Automated call center solutions

- Audio search and indexing tools

- Meeting and podcast transcription platforms
