Why it matters
Sub-50ms TTS would return most of a voice agent's latency budget to transcription and language-model reasoning, but only if the result survives full-stack, independent measurement.
Gradium, the voice AI developer co-founded by Neil Zeghidour (@neilzegh), released a new text-to-speech beta on September 22nd that it says produces its first audio in less than 50 milliseconds without sacrificing quality.
