Blue Asia Labs provides audio performance and speech recognition testing for smart speakers, wearables, TWS earbuds and voice-controlled devices, covering acoustic performance, far-field recognition and voice call quality.
Capability & Accreditation Scope
| Test Object | Reference Standard | Scope & Accreditation |
|---|---|---|
| Audio equipment | ITU-T P.1100; TIA-810 | Audio performance scope |
| Voice interaction systems | ITU-T P.800 / P.835 series | Speech quality assessment |
| In-vehicle audio | EN 50332 | Headphone and volume scope |
What is Audio & Speech Testing?
Voice-interactive products succeed or fail on how well they hear and speak. Our audio lab measures loudness, frequency response, distortion and far-field speech recognition accuracy, and validates call quality end-to-end.
Testing Scope
| Item | Details |
|---|---|
| Acoustic performance | Frequency response, THD, loudness, sensitivity and channel balance |
| Far-field recognition | Wake-word rate, false-accept rate and recognition accuracy at 1m/3m/5m |
| Noise robustness | Recognition accuracy under babble, street, TV and vehicle noise |
| Call quality | POLQA/MOS evaluation for VoIP and cellular voice calls |
| Echo cancellation | AEC performance, double-talk behavior and howling suppression |
| Beamforming | Microphone array directivity and sound source localization accuracy |
Certification Process
- Requirement review — Agree the acceptance criteria with your product and platform teams.
- Acoustic measurement — Controlled acoustic measurements in our audio lab.
- Voice scenario testing — Scripted far-field and noise-scenario recognition testing.
- Optimization report — Tuning recommendations for microphone array and DSP parameters.
Frequently Asked Questions
Do you test far-field speech recognition?
Yes. We run scripted wake-word and command recognition tests at multiple distances and noise levels.
Can you evaluate call quality?
Yes, including POLQA and MOS scoring for VoIP and cellular voice paths.
Do you support headset audio tuning?
Yes. We provide objective measurements and tuning guidance for TWS and headset acoustics.
How long does audio testing take?
Typical projects take 5–10 working days depending on the number of scenarios.
