IA de voz en tiempo real: Agentes Speech-to-Speech con latencia inferior a 200 ms

The legacy pipeline of transcribing speech via Whisper, feeding text into an LLM, and synthesizing audio with ElevenLabs imposes an unavoidable 1200ms+ latency penalty. Modern Speech-to-Speech models tokenize raw audio directly into discrete acoustic latents, delivering human-like sub-200ms conversational responsiveness with natural barge-in interruption handling.

Full-Duplex Audio Codecs (MIMIC, SNAC & EnCodec)

By quantizing continuous speech waveforms into hierarchical codebook indices (RVQ - Residual Vector Quantization), transformers process voice directly as token sequences. This preserves inflection, whispers, laughter, and emotional tone that text-based tokenizers permanently destroy.
