problem with Record step

We are having a problem getting the record step to work correctly. The program goes through the record step so quickly that the beep is not played, and goes on to follow the success path. You can see from the log portion below that the touch-tone buffer is cleared, and that the record step is instantaneous. An empty wave file is created from the step. 2006/10/18 09:50:01.006: [324] Play 2006/10/18 09:50:01.006: Script code is '12557_21' 2006/10/18 09:50:01.006: Script code '12557_21' corresponds to file 'Vox\Eng\Scripts\12557_21.vce' 2006/10/18 09:50:01.006: Playing 'C:\Program Files\TeleFlow\Applications\12557\Vox\Eng\Scripts\12557_21.vce' 2006/10/18 09:50:01.127: Event: ADIEVN_DIGIT_END 2006/10/18 09:50:12.132: Event: VCEEVN_PLAY_DONE, Finished , msec=11060 2006/10/18 09:50:12.132: Play completed. 2006/10/18 09:50:12.132: [437] Run Flowchart 2006/10/18 09:50:12.132: Flowchart is 'MenuSet' 2006/10/18 09:50:12.132: Phomni2==>MenuSet 2006/10/18 09:50:12.132: [100] START 2006/10/18 09:50:12.132: [102] Set Global Variable 2006/10/18 09:50:12.132: Setting global variable '@COUNTER' to '4' 2006/10/18 09:50:12.132: [104] Clear TT 2006/10/18 09:50:12.132: [105] SR Clear Audio 2006/10/18 09:50:12.132: [101] FINISH 2006/10/18 09:50:12.132: Phomni2<==MenuSet 2006/10/18 09:50:12.132: [319] Record 2006/10/18 09:50:12.132: Maximum record time is '0' 2006/10/18 09:50:12.132: Silence TIMEOUT is '' 2006/10/18 09:50:12.132: Empty Silence TIMEOUT defaults to '@TIMEOUT', and evaluates to '3000' 2006/10/18 09:50:12.132: Voice file is 'c:\temp\test1.wav' 2006/10/18 09:50:12.132: Recording 'c:\temp\test1.wav' 2006/10/18 09:50:12.132: Event: ADIEVN_RECORD_DONE, Stopped , nbytes=0 2006/10/18 09:50:12.132: Setting system variable '@RECORD_RESULT' to 'STOPPED' 2006/10/18 09:50:12.132: [337] Set Global Variable 2006/10/18 09:50:12.132: Setting global variable '@D10A' to '1' 2006/10/18 09:50:12.132: [313] Play 2006/10/18 09:50:12.132: Script code is '12557_23' 2006/10/18 09:50:12.132: Script code '12557_23' corresponds to file 'Vox\Eng\Scripts\12557_23.vce' 2006/10/18 09:50:12.132: Playing 'C:\Program Files\TeleFlow\Applications\12557\Vox\Eng\Scripts\12557_23.vce' 2006/10/18 09:50:32.582: Event: VCEEVN_PLAY_DONE, Released , msec=20460 2006/10/18 09:50:32.582: Hanging up

The problem with your record step is indicated in this line from your log: 2006/10/18 09:50:12.132: Maximum record time is '0' You have asked it to record a zero-length file, and therefore it immediately returns with a code of success. You need to supply a "Maximum time recordable" in milliseconds in the properties of the record step. The "Silence Timeout (ms)" field is optional. If you want the recording to terminate when the caller stops speaking. A good figure to use here is 3000 ms (3 seconds). Anything shorter may interpret natural pauses in human speech as an end-of-speech.

Thanks, that took care of the problem. You might want to change the manual though. It states that a setting of '0' means there is no time limit.

Thank-you! You are quite right; the manual entry is incorrect. It should state that leaving the "Maximum time recordable" field empty results in no time limit.

I am having more difficulty with this step. If the caller does not speak before time runs out, it is not following the timeout path. The program follows the success path. 2006/10/19 15:48:02.733: [319] Record 2006/10/19 15:48:02.733: Maximum record time is '180000' 2006/10/19 15:48:02.733: Silence TIMEOUT is '4000' 2006/10/19 15:48:02.733: Voice file '@VOXFILE' evaluates to 'C:\Program Files\TeleFlow\Applications\12557\Messages\1145411.wav' 2006/10/19 15:48:02.733: Recording 'C:\Program Files\TeleFlow\Applications\12557\Messages\1145411.wav' 2006/10/19 15:48:03.013: Event: ADIEVN_RECORD_STARTED 2006/10/19 15:48:03.013: u-Event: ADIEVN_RECORD_STARTED 2006/10/19 15:48:06.989: Record buffer full event: 0 2006/10/19 15:48:06.989: Event: ADIEVN_RECORD_DONE, No Voice , nbytes=63680 2006/10/19 15:48:06.989: No voice detected 2006/10/19 15:48:06.989: Setting system variable '@RECORD_RESULT' to 'NO VOICE' 2006/10/19 15:48:06.989: [337] Set Global Variable 2006/10/19 15:48:06.989: Setting global variable '@D10A' to '1' 2006/10/19 15:48:06.989: [445] Run Flowchart 2006/10/19 15:48:06.989: Flowchart is 'MenuSet'

I am not sure why this is like this. There may be a good reason why is succeeded instead of resulting in Timeout, but I can't think of what that could be. I will get someone to investigate to determine if it is desired (albiet weird) functionality or a bug. In the meantime, check the @RECORD_RESULT variable. As you can see in this line, TeleFlow supplies you with more information about why a recording terminated in this system variable. After your record step, you can use a compare to check for the 'NO VOICE' value.

That works, thanks for your help.
