Smart Speaker Wake-Up Rate Testing Solution

Project Overview

The smart speaker just won't wake up, is it a structural issue? Or an algorithm issue? Or an angle issue? Or an environmental issue? Or an issue with the wake-up phrase?

What kind of algorithm is suitable for use in a café, what kind of algorithm is suitable for use on the subway (a must-consider issue when implanting AI functions in earphones), and what kind of algorithm is suitable for use in a hotel lobby (a consideration for service robots); after the structure and algorithm are determined, how is the wake-up effect at various angles, and how is the wake-up effect under various signal-to-noise ratio conditions, etc. To get the final answers to all of the above questions, testing must be conducted for verification.

Does the company need to recruit a large number of testers during the product development phase to simulate scenarios and conduct manual, inefficient tests? What kind of method can quickly and objectively, automatically, and quantify the testing of the above issues? Megsign will help everyone find the answers.

An Introduction

Quality control needs to be conducted from two aspects:

A. Acoustic Performance Testing

This includes testing the microphone array's frequency response, distortion, acoustic isolation, structural resonance, etc. Megsign has a complete solution and rich practical experience in project implementation, but this is not the focus of today's discussion. Interested friends can follow our public account to review past materials.

B. Wake-Up Rate Testing

Configuration List

Summarize

Whether it's a smart speaker, smart vehicle, smart headphones, smart robots, or any other intelligent device, the primary interface for human-machine interaction is voice. In this emerging industry, whether you are a brand owner, OEM manufacturer, solution provider, or chip supplier, the success rate of your product's wake-up function will directly determine your success or failure. Conducting an objective, comprehensive, meticulous, and quantified test and evaluation of a product is a necessary condition for success, and there are no shortcuts. Megsign will always accompany you, who pursue quality and have dreams for the future, on the road to success, providing audio testing instruments and systems from research and development to mass production.
