log提示模型加载错误：fastspeech2_quan.tflite does not encode a valid TensorFlow Lite model: Mmap of '60' at offset '0' failed with error '22'。 这个项目只是个调用范例，模型的问题需要去问模型作者，这方面的问题我不清楚。

请问你那里还有可以用的模型吗？我是到图片中的链接中去下载的。

[benjaminwan]

如果是这里下载的模型，应该是没问题的，许多人都用过了。 你可以直接下载ChineseTtsTflite-0.5.0-release.apk，运行起来看是不是正常。 https://github.com/benjaminwan/ChineseTtsTflite/releases/tag/0.5.0 如果这个apk是正常的，可以把apk扩展名改为zip，用压缩软件打开，里面的assets里就是模型文件。

可以运行，感谢。
