Simple TTS for JScript

Introduction

Simple TTS for JScript® is a fundamental text-to-speech application using dynamic HTML (DHTML). DHTML allows the use of SAPI automation directly from a web page. To use Simple TTS for JScript, click Speak Text to synthesize the text in the text edit box. You may change the text anytime that the application is not speaking.

Requirements

Microsoft Internet Explorer 5.0 or later is required. If needed, download the latest version of Microsoft Internet Explorer.

An ActiveX® control is used for SAPI automation and some browsers may display a warning about possible interactions between the SAPI control and standard systems. For the sample to run properly this interaction is required. Click Yes to allow this interaction.

Options

There are several options for Simple TTS for JScript.

Text Edit Box

Enter the text to be spoken in this box. Click Speak Text to hear the text spoken. Although the text may be changed while the web page is open, Simple TTS for JScript defaults to the standard phrase upon initial opening.

Speak Text

Rate

Controls the rate of the voice. Click the plus sign ("+") to speed up the spoken rate, or click the subtraction sign ("-") to slow down the rate. The rate will be changed for the next speak attempt. The changes in rate apply only for the current session and are not saved as the current speaking rate for other applications using SAPI.

Volume

Controls the volume of the voice. Click the plus sign ("+") to increase the volume, or click the subtraction sign ("-") to reduce the volume. The volume will be changed for the next speak attempt. The changes in volume apply only for the current session and are not saved as the current speaking rate for other applications using SAPI.

Voice

Audio Output
