Options
Speech recording
This gropup of options allows You to change the following speech
recording parameters:
- Sampling rate (value from 8000 Hz to 44100 Hz)
- Number of bits per sample (8 or 16)
Linear prediction
This gropup of options allows You to change the following
parameters of linear prediction: coefficients calculation:
- Number of linear prediction coefficients (usually value from 20 to 30 is used)
Speech processing
This gropup of options allows You to change the following speech processing
parameters:
- Frame length (integer value - power of 2)
- Analysis step (integer value - power of 2, less or equal to frame length)
Cepstrum
This gropup of options allows You to change the following
parameters of cepstrum calculation:
- Number of triangular filters
- Number of linear scaled filters (of total number of triangular filters)
- Number of cepstrum coefficients
Speech commands names
This gropup of options allows You to change the texts of speech
commands
Speech parameters used for recognition
This gropup of options allows You to change the type of speech parameters:
- Mel-frequency scaled cepstrum coefficients
- Linear prediction power spectrum
- FFT power spectrum
- Mel-frequency scaled Linear prediction power spectrum
- Mel-frequency scaled Linear prediction power spectrum with its first derivative
Parameters visualization
This gropup of options allows You to change the parameters of
spectrum visualization:
- Maximal parameters value
The value of this parameter changes the view of special indicators on the Main Window
Speech recognition
This gropup of options allows You to change the following speech
recognition parameters:
- Rejection threshold (the maximal allowable distance to patterns)
- Type of simularity measure used for recognition: Dynamic Time Warping or
Hidden Marov Models
Speech detection
This gropup of options allows You to change the following speech
detection parameters:
- Speech energy threshold
- Pause energy threshold
The "Setup" button allows you to estimate these parameters
automatically using Microphone setup module
- Minimal non-pause segment length
- Maximal internal pause length
- Maximal speech command length
Game parameters
This gropup of options allows You to change the following Mosic
game parameters:

- Use figures or parts of pictures on Mosaic cells
- Play sounds or during game or not
Training
This gropup of options allows You to change the following
trianing parameters:
