Voice Recording

Interview Voice Recording

When using an automatic dialer you can create voice recordings using the .wav file format. The recordings are stored on the physical dialer hardware*.

* With TCI the default path for recordings is: C:\BellviewTCI\Interviews\<Project ID number>\

Note: If multiple call attempts are made to the same number, each recording will be made in a separate file. A number is added to the end of the file name to indicate the attempt number.

A CATI project-level option can be set to enable whole interview recordings. Recording will start each time the dialer begins to call a number, and will stop each time the call is terminated (when the interview reaches a hangup command in the survey script).

Sectional Voice Recording

You can record sections of an interview by placing start and stop functions at the desired locations within the survey.

StartVoiceRecording(‘label’)

To begin a sectional recording, call StartVoiceRecording in a script node. The recording will continue until either a StopVoiceRecording() function call is made or the interview reaches a hangup command.

When the StartVoiceRecording script is declared, a label must also be included within parenthesis. The label specified is then incorporated into the name of the .wav file for the recorded section.

StopVoiceRecording()

StopVoiceRecording is a function that may be called inside of a script node to end either whole interview or sectional recording.

Script to call StopVoiceRecording function

Although it is necessary to supply a label when starting a new sectional recording, this is not required when stopping the sectional recording. Instead you must use the StopVoiceRecording command with one of the three supported strings… “WholeInterview”, “Sectional” or “Both” as:

StopVoiceRecording(‘WholeInterview’)

StopVoiceRecording(‘Sectional’)

StopVoiceRecording(‘Both’)

Note that these strings are not case sensitive.

Note: It is not always possible to have concurrent whole-interview recordings and sectional recordings for the same interview. This functionality is supported by the Forsta API, but it is down to the dialer vendor to make use of the capability. Neither the Forsta TCI dialer nor the Marketing Systems Group, PRO-T-S® dialer currently support concurrent whole interview + sectional recording. If whole interview recording is enabled then a StartVoiceRecording(‘label’) or StopVoiceRecording() function call will toggle the whole interview recording at the point of execution.
