The TextToSpeechBuilder Application

The TextToSpeechBuilder application allows the user to build a Windows WAVE (*.wav) file from a string of text. The WAVE files created by this application can be used in VoIP applications for playing prerecorded audio to a call party.

This application creates WAVE files with the following characteristics.

• Sample Format: 16-bit linear PCM
• Sample Rate: 8000 or 16000 samples/second
• Number of Channels: 1

To create a WAVE file from text, fill in the settings described below and then click on the Create button.

Settings

Prepend Silence

The Prepend Silence setting specifies the number of milliseconds of silence to generate before the beginning of voice audio.

Text

This setting specifies the text to generate the voice audio for. It may contain multiple sentences and there is no limit on its length.

Append Silence

The Append Silence setting specifies the number of milliseconds to append to the end of the voice audio that is generated.

Sample Rate

Specifies the sample rate. The choices are 8000 or 16000 samples/second.

In general, 8000 samples/second is adequate for most VoIP applications. If "high definition" audio is required and the application is using a wideband codec such as AMR-WB then 16000 samples/second is the better choice.

Voice

Specifies the voice to use. The choices are "Female" and "Male".

File

Specifies the destination of the WAVE file. The user can use the Browse button to select a folder and a file name to write the audio samples to.
