微软文字转语音怎么导出（文字转语音教程详解）

常用的TTS文字转语音有微软、谷歌、科大讯飞，这里分享一下微软的方法。

1、注册账号

地址：https://azure.microsoft.com/zh-cn/services/cognitive-services/text-to-speech/

2、得到终结点和秘钥

3、下载代码调取API

调用方式：本地发送HTTP请求--》微软服务器，认证后---》返回转换的音频到本地。

调用程序：https://github.com/Azure-Samples/Cognitive-Speech-TTS

Samples-Http文件夹下有各种语言如Android, C#, Java, Node.js, PHP, Python,Ruby

这里以Python举例

修改TTSSample.py文件

(1）apiKey = "Your api key goes here"，把引号中的内容替换为STEP2图片中的**1或者**2。

(2)检查代码中终结点是否与STEP2图片中的终结点相同。比如程序中的AccessTokenHost = "westus.api.cognitive.microsoft.com"，其中的“westus”就是终结点。再查看您账户中申请时分配的终结点名称，如STEP2图中的“westus”。若二者一致，则跳至下一步；若不一致，需要修改（只修改代码中的“westus”就行，“.api.com.......”不需要修改）。

同理，程序中“conn = http.client.HTTPSConnection("westus.tts.speech.microsoft.com")”做同样的修改。若您的终结点不是westus，则把程序中的westus替换为您的终结点名称。

终结点有3个：

这一条若不理解，可参看https://docs.microsoft.com/zh-cn/azure/cognitive-services/speech-service/how-to-text-to-speech。

(3)根据https://docs.microsoft.com/zh-cn/azure/cognitive-services/speech-service/rest-apis#authentication的说明，修改程序中X-Microsoft-OutputFormat和输出音频的属性（男声还是女声）。暂时输出音频只支持24khz的采样率。

(4)程序中的“voice.text”后的内容就是希望转成音频的文字内容，可以根据实际需求做修改。

(5)这时就能运行TTSSample.py。程序正常运行的返回值应该为"200 OK"。如果发生错误，则会有以下状态代码：

假设前面的操作都没问题，也得到了200的返回值，那么转换后的音频在哪？答案是在程序的"data"这个变量中。"data"中的数据就是TTS转换后的音频，我们需要把它写为wav格式才能得到最终的音频。具体的操作见文末的代码。

附件：修改后的TTSSample.py文件（当然，您需要把apiKey修改为您的**；检查Python是否含有"wave"这个包）,output.wav就是文本转换后的音频
