阿里云语音合成使用流程完全记录

一.申请阿里云的key和appkey。

因为我已经申请完了,所以直接从网上找个流程,粘贴到这里。如下

语音试听地址:https://ai.aliyun.com/nls/tts

当然也可点击文章头部的语音,看看是否你需要的类型。
注册阿里云这些步骤,我就省略了啊。

阿里云官网:https://cn.aliyun.com/
第一步

1、注册之后点击链接进入控制台:

https://nls-portal.console.aliyun.com/overview

会提醒你开通语音合成,点击即可

2、进入控制台创建一个项目——点击总览或全部项目——【创建项目】

3、创建之后记得保存——appkey至文本,后面会用到

二.安装python SDK

按照下面页面指示进行。

https://help.aliyun.com/document_detail/120699.html?spm=a2c4g.11186623.6.594.22a42bc0iltYNk

在python setup.py install的时候,会遇到下面的错误。

命令行上面内容省略。。。

Installed c:\users\administrator\appdata\local\programs\python\python36\lib\site-packages\alibabacloud_nls_java_sdk-2.0.0-py3.6.egg
Processing dependencies for alibabacloud-nls-java-sdk==2.0.0

解决办法是运行  

pip install incremental==17.5.0

再运行就没有错误了。成功安装。

像下面这样是安装成功了。

修改示例代码,

 

运行出现错误。

查了很久,发现是python版本的问题。

https://*.com/questions/47962516/python-error-10042-pusher-websocket

I saw the same error using a different library that uses websockets. I can see from your description (and link) that Pysher uses websockets.

I found (yet another) websocket client for Python that reported an issue with websockets, specifically with Python 3.6.4: [https://github.com/websocket-client/websocket-client/issues/370]

It references the bug in Python tracker as well [https://bugs.python.org/issue32394]

Upgrading to Python 3.6.5 worked for me. Alternatively, they suggest that upgrading to Windows 10 1703+ should work too (just for completeness; I have not verified this).

所以,不要用python3.6.4  ,后来我下载安装了python3.8.就可以正常运行了。

demo代码如下:

# -*- coding: utf-8 -*-
import threading
import ali_speech
from ali_speech.callbacks import SpeechSynthesizerCallback
from ali_speech.constant import TTSFormat
from ali_speech.constant import TTSSampleRate

class MyCallback(SpeechSynthesizerCallback):
    # 参数name用于指定保存音频的文件
    def __init__(self, name):
        self._name = name
        self._fout = open(name, 'wb')
    def on_binary_data_received(self, raw):
        print('MyCallback.on_binary_data_received: %s' % len(raw))
        self._fout.write(raw)
    def on_completed(self, message):
        print('MyCallback.OnRecognitionCompleted: %s' % message)
        self._fout.close()
    def on_task_failed(self, message):
        print('MyCallback.OnRecognitionTaskFailed-task_id:%s, status_text:%s' % (
            message['header']['task_id'], message['header']['status_text']))
        self._fout.close()
    def on_channel_closed(self):
        print('MyCallback.OnRecognitionChannelClosed')


def process(client, appkey, token, text, audio_name, voice):
    callback = MyCallback(audio_name)
    synthesizer = client.create_synthesizer(callback)
    synthesizer.set_appkey(appkey)
    synthesizer.set_token(token)
    synthesizer.set_voice(voice)
    synthesizer.set_text(text)
    synthesizer.set_format(TTSFormat.WAV)
    synthesizer.set_sample_rate(TTSSampleRate.SAMPLE_RATE_16K)
    synthesizer.set_volume(50)
    synthesizer.set_speech_rate(-200)
    synthesizer.set_pitch_rate(0)
    try:
        ret = synthesizer.start()
        if ret < 0:
            return ret
        synthesizer.wait_completed()
    except Exception as e:
        print(e)
    finally:
        synthesizer.close()

def process_multithread(client, appkey, token, number):
    thread_list = []
    for i in range(0, number):
        text = "这是线程" + str(i) + "的合成。"
        audio_name = "sy_audio_" + str(i) + ".wav"
        thread = threading.Thread(target=process, args=(client, appkey, token, text, audio_name, voice))
        thread_list.append(thread)
        thread.start()
    for thread in thread_list:
        thread.join()

if __name__ == "__main__":
    client = ali_speech.NlsClient()
    # 设置输出日志信息的级别:DEBUG、INFO、WARNING、ERROR
    client.set_log_level('INFO')
    voice = 'AiDa'
    appkey = '6WJEA5Xz45YEI69u'
    token = 'e4c27b7055ba41f49afdc1561c2f7503'
    text = "这里是测试的文字。"
    audio_name = 'sy_audio.wav'
    process(client, appkey, token, text, audio_name, voice)
    # 多线程示例
    # process_multithread(client, appkey, token, 2)
