Echo · AI voicebot testing

Call your voicebot
the way a customer would.

Every prompt tweak, model update or new language can break your bot in front of a customer. Echo calls it like a real caller would and tells you what broke, before they do.

What Echo does

Catch the regression, prove the compliance, find the limit.

Your bot changes constantly, and every prompt, model or language change can regress its intent, leak PII, or fall over under load. Echo catches all three on real calls, with the audit evidence compliance asks for, so a bad release never reaches your customers first.

TTS across accents and languages

German, English, French, Spanish, Italian and more. Multiple voices per language. Or upload your own audio.

Sipfront test bots

Bot-to-bot validation. Our test bot drives full conversational scenarios against your bot. Repeatable across releases.

Sipfront ASR transcription

Built-in transcription with timing per phrase. Validate what the bot actually said, not just whether the call connected.

Intent and guardrail checks

Bot disclosure timing, PII leak detection, encrypted-media validation. Pass/fail on the things regulators ask about.

Concurrent voicebot load

Stress-test the underlying bot infrastructure under realistic concurrent load. Find the ASR or LLM rate-limit before customers do.

EU AI Act audit evidence

Bot-disclosure timing, PII checks, encrypted-media validation, forensic SIP/RTP capture, produced automatically as part of every run.
