Use prompt normalization to match the volume of one or more recorded prompts in a Speech Server application to the volume of an existing .wav file.
The sensible way to set the prompt volume for a speech project is to first normalize recorded prompt volume and then set the text-to-speech (TTS) volume to match the volume of the recorded prompts. For information about setting the TTS prompt volume, see How to: Set TTS Volume.
Match Prompt Volume to an Existing .wav File
In the following procedure a single recorded prompt is used to define the volume for one or more other prompts. The prompt that sets the standard is referred to as the reference prompt. The prompts that are being modified are referred to as the target prompts.
Note
The reference prompt must be correctly aligned. For more information about prompt alignment, see Alignment.
To normalize prompt volume
In Microsoft Visual Studio 2005, open the prompt database that contains the reference prompt, and then record the name of the reference prompt.
Open the prompt database containing the target prompts.
For more information, see How to: Open a Prompt Database.
In the Transcription pane, right-click one or more target prompts, and then click Normalize Wave.
In the Normalize Wave dialog box, click Browse.
In the Select Prompt Database dialog box, select the .promptdb file that contains the reference prompt, and then click Open.
In the Normalize Wave dialog box, enter the wave name of the reference prompt, and then click OK.
