With the development of the mobile Internet, video and live streaming have become mainstream communication methods. Short videos and e-commerce live broadcasts have further bonded people's fragmented time. The user penetration rate is as high as 90.4%, and the e-commerce conversion rate of videos has also risen to 72%. The proportion of usage in each scene has increased across the board.
The intelligent audio equipment supported by relevant hardware has become the first entrance to the intelligent platform. Video content outlets accelerate intelligent audio AI upgrades.
Intelligent voice products expand the traditional usage scenarios. In conferences, speeches, interviews, and live broadcast scenarios, the core of the realization of these functions requires a dedicated MCU chip.
ESP32 has excellent performance and rich peripherals. It integrates Wi-Fi, traditional Bluetooth, and Bluetooth low energy to provide a highly integrated solution that is widely applicable to various IoT applications.
ESP32 audio series development board is based on the design and development of ESP32, ESP32-S2 and ESP32-S3 series chips. It is specially designed for the audio market and is suitable for the development of smart speakers, smart voice robots, voice story machines, and voice control in smart home, smart office and other scenarios. equipment.
The development board provides out-of-the-box voice functions, supports access to a variety of mainstream voice platforms, and meets users' audio development needs.
A dedicated MCU for the intelligent voice market, the ESP32 chip has efficient man-machine voice interaction capabilities and higher computing power, especially in AI intelligent noise reduction and sound pickup.
ESP32 series audio development boards provide advanced Wi-Fi + Bluetooth dual-mode audio solutions, supporting multiple audio playback sources, including HTTP, HLS (HTTP live streaming), SPIFFS, SDCARD, A2DP-Source, A2DP-Sink, HFP, etc. It has the functions of high-definition sound pickup, deep noise reduction, recording transcription and so on.
It is also an AI microphone, which can perform functions such as de-reverberation of human voices, multi-role voice change, etc., allowing consumers to have more unique timbres in broadcasting, karaoke, and game-connected microphones.
ESP32 series audio development boards support functions such as Wi-Fi one-key network configuration, voice wake-up, voice recognition, and cloud platform access, and are suitable for the development of various audio and AIoT applications, such as Wi-Fi and Bluetooth speakers, voice remote controls, Voice robots, smart toys, and smart home devices with voice functions, etc.
The popularity of video content accelerates the upgrade of smart audio AI. Under the trend of video communication, the popularization of smart audio products will quickly become the direction of the industry.
ESP32 integrates antenna switch, RF balun, power amplifier, low-noise amplifier, filter, and power management module. It occupies a small PCB space and can maximize the various functional requirements of practical applications.
At the same time, with the support of the high computing power dedicated MCU chip for intelligent voice, more intelligent audio hardware upgrades will also be presented to the public in a richer form.
ESP-ADF is an audio development framework for ESP32 and ESP32-S2 series chips. Users can easily develop various audio applications based on ESP-ADF and add custom functions to them. In addition, ESP-ADF also provides connection services for various voice platforms, which is convenient for users to directly connect to the cloud platform to develop voice products.
