Why it matters
What happens when AI voice agents
What happens when AI voice agents
aren't tested properly
In voice AI, a single misheard word or broken response isn't just a UX issue, it's a dropped call, a lost customer, or a compliance failure on record.
Speech recognition failures
Accents, background noise and domain-specific vocabulary trip up untested ASR systems, causing misinterpretations that cascade through the entire conversation.
Unnatural or broken dialogue
Poorly timed responses, abrupt interruptions and unhandled silence cause conversations to feel robotic and drive users to hang up.
Incorrect information spoken aloud
A chatbot can be ignored a voice agent speaking wrong policy details, prices or instructions creates immediate trust damage and potential liability.
Telephony & integration failures
Broken PSTN handoffs, failed CRM lookups and dropped transfers leave callers stranded with no resolution and no fallback.
How Testiva protects your AI voice agent
- Voice AI expertise — Our QA engineers specialise in conversational voice systems and telephony pipelines, not generic software or chatbot testing.
- Real audio simulation testing — We test with diverse voice profiles, accents, noise conditions and speaking speeds to surface ASR failures before real callers do.
- End-to-end call flow validation — Full conversation path coverage including hold, transfer, escalation, fallback and post-call webhook triggers.
- Latency & turn-taking QA — Response timing, barge-in handling, silence detection thresholds and interruption recovery tested to human conversation standards.
- Compliance & recording validation — Consent prompt delivery, call recording triggers, PII redaction in transcripts and audit trail completeness tested by default.
What we test
Core components of an AI voice agent we cover
Every layer that affects call quality is validated, stress-tested, and verified across telephony providers, accents and real-world audio conditions.
Speech recognition & ASR accuracy
Validating accurate speech recognition across accents, noise conditions and domain-specific vocabulary.
Natural language understanding
Testing reliable intent detection, entity extraction and spoken language understanding accuracy.
Response generation & TTS quality
Ensuring natural, clear and brand-aligned voice response generation.
Conversation flow & dialogue management
Verifying smooth multi-turn conversations, context retention and recovery from misunderstood inputs.
Latency & turn-taking behaviour
Testing responsive interactions, interruption handling and natural conversational timing.
Escalation & human handoff
Validating accurate transfer logic and seamless context handoff to human agents.
Telephony & platform integration
Ensuring reliable telephony connectivity, call handling and cross-platform integration stability.
Compliance & privacy enforcement
Testing consent handling, PII protection and regulatory compliance across voice interactions.
Performance & concurrency
Verifying stable voice agent performance, scalability and failover reliability under high call volumes.

Common questions
We run audio test suites across accent profiles, noise conditions, and speaking rates measuring word error rate per segment.
We evaluate intent classification on transcribed speech variations, including disfluencies, pauses, and informal spoken language.
We run spoken dialogue evaluations measuring context retention, topic transition handling, and recovery from misrecognised input.
We test escalation trigger conditions, transfer quality, and context handoff accuracy when the voice agent reaches its limits.
We measure end-to-end response latency under load, with thresholds informed by conversational UX standards for voice interfaces.
We measure ASR and NLU accuracy across age, gender, accent, and language background reporting parity gaps by demographic.
