([简体中文](./README_cn.md)|English) # Speech Server ## Introduction This demo is an implementation of starting the voice service and accessing the service. It can be achieved with a single command using `paddlespeech_server` and `paddlespeech_client` or a few lines of code in python. ## Usage ### 1. Installation see [installation](https://github.com/PaddlePaddle/PaddleSpeech/blob/develop/docs/source/install.md). It is recommended to use **paddlepaddle 2.2.2** or above. You can choose one way from meduim and hard to install paddlespeech. ### 2. Prepare config File The configuration file can be found in `conf/application.yaml` . Among them, `engine_list` indicates the speech engine that will be included in the service to be started, in the format of `_`. At present, the speech tasks integrated by the service include: asr (speech recognition), tts (text to sppech) and cls (audio classification). Currently the engine type supports two forms: python and inference (Paddle Inference) **Note:** If the service can be started normally in the container, but the client access IP is unreachable, you can try to replace the `host` address in the configuration file with the local IP address. The input of ASR client demo should be a WAV file(`.wav`), and the sample rate must be the same as the model. Here are sample files for thisASR client demo that can be downloaded: ```bash wget -c https://paddlespeech.bj.bcebos.com/PaddleAudio/zh.wav https://paddlespeech.bj.bcebos.com/PaddleAudio/en.wav ``` ### 3. Server Usage - Command Line (Recommended) ```bash # start the service paddlespeech_server start --config_file ./conf/application.yaml ``` Usage: ```bash paddlespeech_server start --help ``` Arguments: - `config_file`: yaml file of the app, defalut: ./conf/application.yaml - `log_file`: log file. Default: ./log/paddlespeech.log Output: ```bash [2022-02-23 11:17:32] [INFO] [server.py:64] Started server process [6384] INFO: Waiting for application startup.
