What is Text to Speech (TTS)?
Text to speech, or TTS, is the technology that converts written text into spoken audio. It is the final step in a voice AI pipeline, delivering the system's response back to the caller as natural sounding speech.
How Text to Speech (TTS) works
Modern TTS systems use neural network models that generate speech waveforms from text input. They handle pronunciation, intonation, pacing, and emphasis to produce output that sounds close to a human speaker. Quality is measured by Mean Opinion Score (MOS), where 5.0 is indistinguishable from human speech. Top commercial systems score 4.2 to 4.5.
Why Text to Speech (TTS) matters for enterprise
TTS quality directly affects caller trust and conversation completion rates. Robotic or unnatural sounding voice responses cause callers to hang up or request a human agent. For Indian enterprises, TTS must handle multiple languages and the transition between them within a single response.
How ARCA handles Text to Speech (TTS)
