写一个unity的文字合成语音的API这里是API的接口地址和参数text的内容为下面参考示例中_callback参数 httpsgenshinvoicetopapispeaker=胡桃&text=你好&format=wav&length=1&noise=05&noisew=09&sdp_ratio=02 using System;using SystemCollections;using Sy

这是一个Unity中使用文字合成语音的API的示例代码。该API的接口地址和参数可以在代码中自定义，示例中的接口地址为"https://genshinvoice.top/api"，参数为"speaker"、"text"、"format"、"length"、"noise"、"noisew"和"sdp_ratio"。具体使用方法是调用SpeechToText方法并传入音频文件和回调函数，回调函数将接收合成语音的文本结果。
