推荐答案

您可以在网站上找到的简单解决方案使用Google Speech API将语音从音频文件转换为文本。



困难的方法：你必须知道你的输入格式，而不是从它找到一个转换器到你的LINEAR16格式。有时，3个步骤的转换效果最好：

The easist solution you may find with the website Convert speech from an audio file to text using Google Speech API.

The hard way: you must know your input format and than find a converter from it to your LINEAR16 format. Sometimes a conversion in 3 steps for works best like:

Your input format => meta format (like PCM) => LINEAR16

因为你可能会找到一些转换器或代码。



在Javascript中使用as64字符串编码该字节缓冲区一块蛋糕，有人已经为你烘焙了。

because you may find some converter or code.

Encoding that byte buffer with as base64 string in Javascript is a piece of cake which somebody has already baked for you.
