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.
It is recommended to use paddlepaddle 2.2.1 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 <speech task>_<engine type>
.
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)
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:
wget -c https://paddlespeech.bj.bcebos.com/PaddleAudio/zh.wav https://paddlespeech.bj.bcebos.com/PaddleAudio/en.wav
3. Server Usage
-
Command Line (Recommended)
# start the service paddlespeech_server start --config_file ./conf/application.yaml

4. ASR Client Usage
Note: The response time will be slightly longer when using the client for the first time
-
Command Line (Recommended)
paddlespeech_client asr --server_ip 127.0.0.1 --port 8090 --input ./zh.wav
Usage:
paddlespeech_client asr --help
Arguments:
server_ip
: server ip. Default: 127.0.0.1port
: server port. Default: 8090input
(required): Audio file to be recognized.sample_rate
: Audio ampling rate, default: 16000.lang
: Language. Default: "zh_cn".audio_format
: Audio format. Default: "wav".
Output:
[2022-02-23 18:11:22,819] [ INFO] - {'success': True, 'code': 200, 'message': {'description': 'success'}, 'result': {'transcription': '我认为跑步最重要的就是给我带来了身体健康'}} [2022-02-23 18:11:22,820] [ INFO] - time cost 0.689145 s.
-
Python API
from paddlespeech.server.bin.paddlespeech_client import ASRClientExecutor import json asrclient_executor = ASRClientExecutor() res = asrclient_executor( input="./zh.wav", server_ip="127.0.0.1", port=8090, sample_rate=16000, lang="zh_cn", audio_format="wav") print(res.json())
Output:
{'success': True, 'code': 200, 'message': {'description': 'success'}, 'result': {'transcription': '我认为跑步最重要的就是给我带来了身体健康'}}
5. TTS Client Usage
Note: The response time will be slightly longer when using the client for the first time
-
Command Line (Recommended)
paddlespeech_client tts --server_ip 127.0.0.1 --port 8090 --input "您好,欢迎使用百度飞桨语音合成服务。" --output output.wav
