xAI (Grok) for AI voice agents

xAI (Grok) is one of the voices you can run a Telenow AI voice agent on. Grok streaming TTS — expressive voices + your xAI voice clones, speech tags (laughs, whispers, pauses); μ-law 8k telephony, 24k HD on web calls. Give your agent a xAI (Grok) voice for natural, streaming speech the caller can't tell from a human. Mix and match it with any LLM, STT, TTS and carrier — Telenow is component-level, so you're never locked in.
