4.3.2 Automatic Mode

To run the CSP demo in automatic mode, type:

cspdemo -c<no. of channels> -i<no. of iterations> -l<log name> 

For example, to run a 12-channel test (one iteration is the default) and log the results in autotest.log file, type:

cspdemo -c12 -lautotest.log 

The automatic mode is a multi-channel demo that uses the number of CSP channels specified by you in the command line. Channels are paired, with one channel playing a prompt (also called the stimulus channel) while the other partner channel simulates a user interrupting the prompt (the channel being tested).

For example, Channel 1 is paired with Channel 2. Channel 2 plays a prompt. Channel 1 waits one second and plays its own prompt to simulate barge-in. Channel 2 detects the barge-in, stops its prompt, and begins recording using ec_reciottdata( ). After each iteration, the two partner channels change roles. Event generation and other messages are saved to the log file as the demo progresses.
