到目前为止，我已经测试了一个非常小的 16 kHz 和 48 kHz 的音频文件。我很想进行更大规模的测试，但正如你所知，这需要花钱。
48 kHz 采样率提供了更好的结果。但是，在文档中说最好是 16 kHz
所以我有点困惑
flac这里是我用 Google Speech to Text API 测试的 16 kHz 和 48 kHz文件
16 kHz：https ://drive.google.com/file/d/1MbiW3t86W68ZqENtDqD4XdNmEV7QZbZA/view?usp=sharing
48 kHz：https ://drive.google.com/file/d/1aLN1ptMJBwuYc6FdAk6CxcK1Ex4jI3vh/view?usp=sharing
在这里制作的成绩单

视频的原始采样率为 48 kHz
那么任何专家或员工都可以对此发表评论吗？
这些是我用来ffmpeg组成flac文件的 16 kHz 和 48 kHz 命令
-af aformat=s16:16000:mono
-af aformat=s16:48000:mono
