Customize Voice Solutio & AI Voice Series
Our customized AI voice audio motherboards boast extensive applications, comprehensively covering all audio-enabled terminal products including the automotive equipment series, consumer electronics series, smart voice device series, AI voice device series, Bluetooth audio series, children’s audio product series, smart wearable product series, medical instrument equipment, pet device series, beauty equipment series, and household appliance series.
Tailored to the unique demands of different industry scenarios, we have built a functional modular customization system — based on the design logic of standardized core modules and optional extended functions. While ensuring core performance such as audio transmission stability and acoustic fidelity, it precisely matches the structural dimensions, appearance, and functional requirements of devices across various industries (e.g., anti-interference requirements for automotive scenarios, low-power consumption standards for medical equipment, and safety and compliance requirements for children’s products).
This approach not only flexibly controls the cost of motherboard customization (adding or removing audio modules such as Bluetooth, noise reduction, and AI voice interaction on demand to avoid waste from redundant functions) but also leverages a mature standardized customization process to help customers quickly complete product iteration and market launch.
Whether for consumer-grade smart devices, industrial-grade communication terminals, or professional medical instruments, our customized audio motherboards deliver the triple value of scenario-specific adaptation, stable and reliable performance, and balanced cost-efficiency, serving as the core hardware backbone for audio motherboards in industries worldwide.
