Language files
If you want to speak english, you need to get the english language model and the english acoustic model.
You will need to put the acoustic model into scribe/hmm
, and the language model into scribe/lm
.
The filetree should look like this for english:
scribe
├── dict
│ └── cmu07a.dic
├── hmm
│ ├── feat.params
│ ├── feature_transform
│ ├── mdef
│ ├── means
│ ├── mixture_weights
│ ├── noisedict
│ ├── README
│ ├── transition_matrices
│ └── variances
├── lm
│ └── cmusphinx-5.0-en-us.lm.dmp
For other languages, check here, or see below on training your own model. If you use different language models, acoustic models, or dictionaries, you will want to change these paths in recognizer.py
:
HMDIR = os.path.join(BASE_PATH, "hmm")
LMDIR = os.path.join(BASE_PATH, "lm/cmusphinx-5.0-en-us.lm.dmp")
DICTD = os.path.join(BASE_PATH, "dict/cmu07a.dic")
Run
To run, you just have to:
cd speech-recognizer
python recognizer.py
You should be able to talk for a few seconds, after which it will spend some time processing, and the show you what you said.
Configure
There are some options that you can modify at the top of recognizer.py
. The easiest one to modify is RECORD_SECONDS
.
More reading
To find out more, read up on sphinx.
You can train the language models to make them more accurate, use unsupported languages, or be more domain-specific.
