Hi, I am a researcher and am trying to install DeepSpeech to simplify and speed up transcription of audio recordings of interviews. I have managed to install deepspeech based on some guidelines I found on the web.

When I try to run deepspeech, I get some confusing errors:

Command:

deepspeech --model models/output_graph.pbmm --alphabet models/alphabt.txt --lm models/lm.binary --trie models/trie --audio interviewCloete.wav

Output: usage: deepspeech [-h] --model MODEL [–scorer SCORER] --audio AUDIO

[–beam_width BEAM_WIDTH] [–lm_alpha LM_ALPHA]

[–lm_beta LM_BETA] [–version] [–extended] [–json]

[–candidate_transcripts CANDIDATE_TRANSCRIPTS]

deepspeech: error: ambiguous option: --lm could match --lm_alpha, --lm_beta

I then specified lm_alpha:

deepspeech --model models/output_graph.pbmm --alphabet models/alphabt.txt --lm_alpha models/lm.binary --trie models/trie --audio interviewCloete.wav

I then get the following output:

usage: deepspeech [-h] --model MODEL [–scorer SCORER] --audio AUDIO

[–beam_width BEAM_WIDTH] [–lm_alpha LM_ALPHA]

[–lm_beta LM_BETA] [–version] [–extended] [–json]

[–candidate_transcripts CANDIDATE_TRANSCRIPTS]

deepspeech: error: argument --lm_alpha: invalid float value: ‘models/lm.binary’

I am not a coder or a hacker, so I don’t know how to resolve this. Can anyone assist?

Many thanks in advance!
