chinese voice error?

[opentld]

platform: windows10, vs2019, cuda10.2
testing english model correctly, but testing chinese model, get wrong output:
the input chinese voice is : 测试，测试，but the output is: 鍘邋邋

I record .m4a file from windows 'Voice Recorder' in Chinese, and then convert it to .wav:
audio_format=6
num_channels=2
sample_rate=16000 (desired=16000)
bits_per_sample=8
res.buffer_size=291939
it seems that the codes run correctly:

fseek(wave, 40, SEEK_SET); rv = fread(&res.buffer_size, 4, 1, wave);
fprintf(stderr, "res.buffer_size=%ld\n", res.buffer_size);

fseek(wave, 44, SEEK_SET);
res.buffer = (char*)malloc(sizeof(char) * res.buffer_size);
rv = fread(res.buffer, sizeof(char), res.buffer_size, wave);

res.buffer_size is 291939, means that voice file has been read.

BUT when I convert the .m4a flie to .wav, using mono channel:
audio_format=1
num_channels=1
sample_rate=16000 (desired=16000)
bits_per_sample=16
res.buffer_size=62

the result is: ?

the res.buffer_size=62, it looks like the voice file was not read correctly.

why????
