In recent years, major motorcycle manufacturers such as Harley-Davidson and Honda have gradually equipped their models with in-vehicle entertainment systems and voice assistants. Additionally, more and more general motorcycle riders are starting to use helmet microphones to perform various “motorcycle voice assistant” functions while riding, such as voice search for navigation, music playback control, and hands-free calls via Bluetooth connection.
Client Background and Challenges
In this case study, the client is an international supplier of automotive voice software, primarily focusing on developing original equipment for automakers. With years of experience in “automotive voice assistant” products, this was their first foray into “motorcycle voice assistant” products. During the initial evaluation phase of the project, the client encountered numerous new challenges. These challenges had the potential to significantly impact the activation rate and recognition success rate of the voice assistant during riding, as well as the user experience and satisfaction after the product launch.
Examples of these challenges include:
- Different use scenarios compared to cars: The wind noise during riding is far greater than the interior noise in cars, severely affecting activation and recognition rates.
- Compatibility with aftermarket products: Compatibility with various types, brands, and models of Bluetooth helmet microphones.
- Data communication and collaboration across platforms: Integration between cloud computing, in-vehicle apps, different systems/brands of smartphones, and Bluetooth helmet microphones.
Solutions
To quickly address these pressing challenges and needs, the client sought the expertise of Allion Labs’ consulting team. After in-depth discussions, the Allion Labs team shared several critical conditions for user scenario simulation and verification, including:
Compatibility with Aftermarket Products
- Differences in audio pickup performance and compatibility among various brands and models of Bluetooth microphones.
- Compatibility with different systems (Android/iOS) and models of smartphones.
Impact of Different Usage Scenarios
- Effects of road noise in various speed environments (e.g., suburban, urban, highways).
- Influence of different helmet designs (e.g., full-face, half-face).
- Differences in microphone placement (e.g., adhesive microphones, flexible arm microphones).
Impact of Different Command Contents
- Differences in recognition success rates for various voice commands (e.g., command length, phrasing differences, commands with numerical and location information).
- Recognition success rate differences based on gender and voice characteristics (e.g., male vs. female voices).
To prepare for the key conditions of the user scenario simulation, Allion Labs recorded actual riding road noise from various environments. Using sound field reconstruction technology, they simulated noise environments and established an “Environmental Noise Sound Field Simulation Test Laboratory” to enhance the effectiveness of user scenario simulation and verification.

Implementation Benefits
Thanks to the acoustic measurement data and related consulting services provided by Allion Labs, the client significantly improved the speed and efficiency of problem-solving during the project development process. Not only was the overall verification schedule shortened by nearly 30 days, but the recognition success rate and stability of their voice product were also enhanced. This substantially reduced the risks of customer complaints and hidden costs related to repeated verifications after the product launch
