Did not successfully decode file BAC009S0002W0125, len = 629

这是个什么问题？

同问，也遇到这么个问题

[HW140701]

我也是遇到这个问题

@HW140701 对于这个问题，我在montreal-forced-aligner中看到过一个解决办法：逐渐调大beam的值，直至合适为止，可以得到textgrid文件

I install the repo successful, but I meet the error as follows. when use it. Do you know how to solve it?

This works for me. Experiment as follows:

1. merge two sample files with ffmpeg

ffmpeg -i BAC009S0002W0122.wav -i BAC009S0002W0123.wav -filter_complex '[0:0][1:0]concat=n=2:v=0:a=1[out]' -map '[out]' merged.wav

2. create a new playlist called merged.lst with content:

merged merged.wav

3. also create a merged transcript called merged.txt

4. in run.sh, execute the following script

speech-aligner --config=conf/align.conf merged.lst merged.txt merged.out

(this should fail)

5. now edit align.conf, set:

--beam=40 --retry-beam=80

(now it should work)

I also tested another audio file of 49 seconds. In order to finish align, the beam parameter has to be increased to 10240, and it runs much slower.

I guess that's why input audio must be a play list. By design the aligner is intended to process a list of sentences, each in a separate audio file, in which case a beam of 20 or 40 should be enough.
