Voicetest adds live audio call simulation for voice agent testing

By PulseAugur Editorial · [1 sources] ·

Voicetest has introduced a new feature that simulates live audio calls for testing voice agents, addressing a critical gap in traditional text-based simulations. This new capability allows developers to evaluate how well their agents perform in real-world audio conditions, capturing issues where the intended LLM output is distorted by Text-to-Speech (TTS) or misinterpreted by Speech-to-Text (STT) on the caller's end. By comparing the intended text with the transcribed 'heard' text from actual audio, Voicetest can identify and flag regressions in pronunciation, number interpretation, and other critical conversational elements that text-only evaluations miss. AI

IMPACT Enables more robust testing of voice agents, improving the reliability of LLM-powered conversational interfaces in real-world audio environments.

    Your Agent Said It Right. Did the Caller Hear It? Live Call Testing in Voicetest

    <p>A voice agent can pass every text simulation and still fail on a real call. The LLM produces the right sentence, and then the speech pipeline mangles it: a phone number read as a quantity, a drug name the TTS voice can't pronounce, an appointment time that STT on the other end…
