Summary
It’s for operators and developers who want high-volume production voice agents without building the surrounding stack from scratch. Most voice stacks stitch together three APIs—speech-to-text, a language model, and text-to-speech—often with each stage hosted by a different provider. Real calls come with low-quality telephony audio, background noise, strong accents, interruptions, and callers who change their minds mid-sentence. The team trained Grok Voice on those calls. τ-voice Bench measures agents under the same conditions.
