- Basic Example:
This example demonstrates how to use ADF to play the audio generated by Baidu’s online text-to-speech service. It uses Chinese text by default, but also supports other languages. For more technical information, please go to Baidu text-to-speech documentation.
Below is the pipeline that obtains the MP3 audio generated by Baidu’s online text-to-speech service.
[baidu_tts_server] ---> http_stream ---> mp3_decoder ---> i2s_stream ---> [codec_chip]
This example runs on the boards that are marked with a green checkbox in the table. Please remember to select the board in menuconfig as discussed in Section Configuration below.
This example supports IDF release/v3.3 and later branches. By default, it runs on ADF's built-in branch $ADF_PATH/esp-idf.
The default board for this example is ESP32-Lyrat V4.3. If you need to run this example on other development boards, select the board in menuconfig, such as ESP32-Lyrat-Mini V1.1.
menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1
Connect to a Wi-Fi network by running menuconfig and then filling in the network information.
menuconfig > Example Configuration > `WiFi SSID` and `WiFi Password`
In addition, you need to apply for a TTS application at Baidu’s online TTS page, and fill in your API Key and Secret Key respectively in menuconfig so as to authenticate with the Baidu TTS server.
menuconfig > Example Configuration > `Baidu speech access key ID` and `Baidu speech access secret`
Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with your board's serial port name):
idf.py -p PORT flash monitor
To exit the serial monitor, type Ctrl-].
See ESP-IDF Programming Guide for full steps to configure and build an ESP-IDF project.
- After the example starts running, it first tries connecting to the preset Wi-Fi network, and then authenticates with the Baidu TTS server. If the authentication succeeds, it will ask the server to convert the Chinese text
欢迎使用乐鑫音频平台，想了解更多方案信息请联系我们into speech. Finally, the server returns the speech as an MP3 audio file. The log is as follows:
