Our solutions for your SpeechTech app testing challenges

Solving the issues that slow down accuracy, performance, and real-world reliability.

Real-world audio variability

Challenge

Up to 70% of ASR issues come from noise, accents, and device differences.

Solution

Diverse audio datasets, real-environment simulations, and device-level validation to maintain accuracy outside the lab.

Latency under load

Challenge

A 150–200 ms delay can break real-time transcription or commands.

Solution

End-to-end load testing across streaming, ASR, and NLP layers to keep responses fast at peak traffic.

Multilingual accuracy gaps

Challenge

Dialect and code-switching can cause 30–45% accuracy drops.

Solution

Balanced multilingual corpora and edge-case validation to strengthen global performance.

Model drift after updates

Challenge

Small model changes often degrade wake-word detection or punctuation.

Solution

ML-focused regression suites and inference comparisons to catch drift early.

Intent and context errors

Challenge

Over 40% of voice assistant failures happen due to misinterpreted context.

Solution

Multi-turn conversation testing and prosody-driven scenarios to improve intent understanding.

Integration issues across the stack

Challenge

Most failures happen between ASR → NLP → business logic.

Solution

Deep integration testing and workflow validation across CRMs, IVRs, and enterprise systems.
