OpenAI Whisper for AI voice agents
OpenAI Whisper is one of the speech-to-text engines you can run a Telenow AI voice agent on. Higher accuracy, non-streaming — better for batch. Use OpenAI Whisper to transcribe the caller in real time so your agent understands every word, even with accents and code-switching. Mix and match it with any LLM, STT, TTS and carrier — Telenow is component-level, so you're never locked in.
