Equipped with a microphone for clear audio acquisition and a built-in speaker for high-quality audio feedback. It supports mid-session voice interruption, allowing for flexible interruption and quick response to new commands during recognition. Integrated AEC (Echo Cancellation) effectively removes echoes and noise interference, improving recognition accuracy. The product comes preloaded with 53 English wake-up and feedback command words and supports activating the device through UART commands or voice keyword triggers. Users can customize recognition words in \u003cstrong\u003eChinese, English, Japanese, and Korean\u003c\/strong\u003e by regenerating firmware, supporting up to 300 command words. The device communicates via a UART interface and allows switching between different UART pins through a DIP switch. It is ideal for AI assistants, smart homes, security monitoring, automotive systems, robotics \u0026amp; smart hardware, and healthcare applications — a perfect choice for intelligent voice interaction.\u003c\/p\u003e\n\u003ch2 id=\"features\" data-id=\"Features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIntelligent offline voice module\u003c\/li\u003e\n\u003cli\u003eAEC noise reduction processing\u003c\/li\u003e\n\u003cli\u003eBuilt-in 53 English commands; support up to 300 commands\u003c\/li\u003e\n\u003cli\u003eUART communication interface\u003c\/li\u003e\n\u003cli\u003eSupport for custom wake-up words\u003c\/li\u003e\n\u003cli\u003eFirmware burning via reserved USB Type-C interface\u003c\/li\u003e\n\u003cli\u003eEquipped with microphone and built-in speaker\u003c\/li\u003e\n\u003cli\u003eDevelopment Platform\n\u003cul\u003e\n\u003cli\u003eUiFlow2\u003c\/li\u003e\n\u003cli\u003eArduino\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"includes\" data-id=\"Includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Module ASR\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"applications\" data-id=\"Applications\"\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAI Assistant\u003c\/li\u003e\n\u003cli\u003eSmart Home\u003c\/li\u003e\n\u003cli\u003eSecurity Monitoring\u003c\/li\u003e\n\u003cli\u003eVehicle System\u003c\/li\u003e\n\u003cli\u003eRobotics \u0026amp; Smart Hardware\u003c\/li\u003e\n\u003cli\u003eHealthcare\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"specifications\" data-id=\"Specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAI Voice Chip\u003c\/td\u003e\n\u003ctd\u003eCI1302\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommand Words\u003c\/td\u003e\n\u003ctd\u003eUp to 300 commands supported; 53 preset commands from factory\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWake-up Method\u003c\/td\u003e\n\u003ctd\u003eVoice keyword or UART serial communication to activate device\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMicrophone\u003c\/td\u003e\n\u003ctd\u003eAnalog microphone, model GMI4527P-2C-32db\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeaker\u003c\/td\u003e\n\u003ctd\u003eChamber speaker 8Ω@0.8W (used for wake-up feedback output)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eUART serial communication, default baud rate: 115200@8N1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise Reduction\u003c\/td\u003e\n\u003ctd\u003eAEC echo cancellation noise reduction\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWake-up Range\u003c\/td\u003e\n\u003ctd\u003eAmbient noise 40dB: up to 6.4m \u003cbr\u003eAmbient noise 54dB: up to 1.8m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eStandby: DC 5V@52.14mA \u003cbr\u003eWorking: \u003cbr\u003eLow volume: DC 5V@43.38mA \u003cbr\u003eMedium volume: DC 5V@85.26mA \u003cbr\u003eHigh volume: DC 5V@161.34mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e54.0 x 54.0 x 13.1mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e15.2g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e132.0 x 95.0 x 13.1mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e28.9g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n → DOCUMENTS \n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":52214819619104,"sku":"bza1787247242493","price":6.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/m5stack-asr-module-ci1302_1.webp?v=1787247248","url":"https:\/\/www.elmwoodbasket.shop\/products\/m5stack-asr-module-ci1302","provider":"My Store","version":"1.0","type":"link"}
