pocketsphinx python
Pocketsphinx is a speech recognition engine developed by Carnegie Mellon University. It provides a simple API for performing speech recognition in Python. To use Pocketsphinx in Python, you can follow these steps:
1. Install the required dependencies:
```
pip install pocketsphinx
```
2. Download the necessary language model and acoustic model files from the Pocketsphinx website.
3. Import the pocketsphinx module in your Python script:
```
import pocketsphinx
```
4. Configure the recognizer with the language model and acoustic model files:
```
config = pocketsphinx.Decoder.default_config()
config.set_string('-hmm', 'path/to/acoustic/model')
config.set_string('-lm', 'path/to/language/model')
config.set_string('-dict', 'path/to/dictionary')
decoder = pocketsphinx.Decoder(config)
```
5. Open an audio file or start recording audio from a microphone:
```
decoder.start_utt()
with open('path/to/audio/file', 'rb') as f:
audio = f.read()
```
6. Decode the speech and retrieve the recognized text:
```
decoder.process_raw(audio, False, True)
decoder.end_utt()
recognized_text = decoder.hyp().hypstr
```
Please note that the paths to the language model, acoustic model, and dictionary files need to be provided correctly for Pocketsphinx to work properly.
