As a pioneer in offline speech recognition module solutions, Dusun IoT has been deeply cultivating the industry for nearly two decades. With long-term technical accumulation and keen market insights, we have provided strong support for many well-known global home appliance brands, helping their smart home products rejuvenate and gain a competitive edge in the fierce market competition.
Background
A world-renowned home appliance brand partnered with Dusun IoT to adopt our advanced AI offline speech recognition modules into their appliances. This collaboration elevated the voice control capabilities of their heaters from simple “listening” to a deeper level of “understanding,” enabling precise responses to every user request, significantly enhancing their user convenience and satisfaction.
However, while enjoying the convenience brought by voice control, both the brand and Dusun IoT keenly observed a new user demand: in certain specific scenarios, such as when family members are resting or in environments that require quiet, frequent voice interactions can become an unnecessary disturbance, affecting the peace and comfort of family members.
Based on this, Dusun IoT innovatively introduced a mobile-app-control function, creating a dual control mode of “sound” and “silence” for the heater products, meeting the diverse needs of consumers for appliance control in different scenarios.
How Dusun IoT’s Speech Recognition Module and Mobile Applications Control Home Appliance?
Dusun IoT’s home appliance voice control solution integrates an AI offline speech recognition module into heaters. This module can instantly parse complex voice commands and quickly transmit control signals to the heater’s main control system, enabling precise control of various heater functions and providing users with an intelligent control experience.
At the same time, the accompanying mobile app can transmit data to the built-in offline voice module via Bluetooth. After processing by the voice module, the results are sent to the main control and synchronized to the mobile app immediately.
This dual voice control method allows users to remotely control the heater through the mobile app, including power on/off, precise temperature adjustment, personalized timing settings, fine adjustment of heating levels, and convenient light switch control. It also allows users to easily achieve all the above functions through offline voice commands, realizing the function of dual-mode control.
It is particularly worth mentioning that we have specially added a switch option for the voice function, allowing users to freely turn the voice control function on or off according to the actual situation, avoiding potential interference from voice interaction in inappropriate situations and ensuring a harmonious and peaceful home environment.
What is Offline Speech Recognition?
Offline speech recognition is a technology that recognizes and converts speech signals locally on a device without requiring an internet connection or cloud-based services.
In the process of handling user voice commands, when a user says “turn on the heater”, the sound data is first captured by a microphone array. This data then undergoes acoustic front-end processing for noise reduction and enhancement to improve the accuracy of speech recognition. The processed sound data is subsequently fed into an offline speech recognition engine, which quickly parses the command and generates corresponding control signals. These control signals are transmitted directly to the heater’s main control unit via a UART serial port, ultimately executing the command to turn on the heater.
Furthermore, Dusun IoT’s offline speech recognition module also supports mobile app sending commands to the voice module via Bluetooth, which the voice module then forwards to the main control unit, enabling dual-mode control. This design not only maintains the convenience of traditional voice control but also adds the flexibility of remote control via mobile apps, meeting the users needs in various scenarios.
How to Improve the Recognition Accuracy of Voice Recognition Modules?
AI-based Noise Reduction
Dusun IoT’s offline voice modules employ cutting-edge AI noise reduction algorithms. Firstly, through front-end signal preprocessing, background noise and echo are effectively filtered out. Subsequently, the algorithm deeply analyzes and adapts to the device’s specific white noise, significantly improving recognition accuracy even in noisy environments. The optimization of sound quality and the continuous improvement of algorithms ensure that even in long-distance or complex scenarios, the voice chip can accurately capture and recognize user commands, enhancing recognition accuracy and response speed.
NLP Natural Language Processing
In addition to powerful noise reduction capabilities, Dusun IoT’s speech recognition modules are also equipped with NLP natural language processing technologies, allowing users to interact in a more fluent and natural language without the need to follow strict command formats, making voice control more humanized and convenient.
Can a Speech Recognition Module Sync Its Status with a Mobile App?
To enhance user experience, Dusun IoT’s speech recognition modules have achieved real-time synchronization between the voice recognition module and the mobile app status. By adjusting the heater’s temperature through voice commands, the mobile app can quickly respond and display the latest status in real-time, allowing users to keep track of the operation of their home devices at any time.
