Text-to-Speech I/O Device for V+ (Windows 7)

Part Number: TTS2DEV-X732

Text-to-Speech I/O Device for V+(Windows XP)

Part Number: TTS2DEV-X86

This device enables users to use V+, a visual programming language, to produce dynamic text to speech based on the value of ports in a design.  Typical uses for this device are ATIS (Automatic Terminal Information Service) used in flight simulation.

A text template file must be provided the contains the basic speech that can include tags that refer to ports in the V+ design or speech controls that can alter the dynamics of the text to speech engine.  Also, the user can specify a dynamic filename via V+ ports in order to switch templates in real-time.

The Text to Speech Device is Now Installed with Multiple Channels

SimPhonics has extended the Text-to-Speech I/O Device for V+, used primarily for Automatic Terminal Information Service (ATIS) broadcast simulations, to include the ability to produce multiple channels. For example, most aircraft are equipped with at least two COMM radios, which can tune two different ATIS frequencies. SimPhonics new audio systems can now simulate up to eight different streams of dynamic speech. The crew can now listen to two ATIS stations simultaneously, additional channels can be used for lesson plans, ground controlled approach, notice to airman, etc.

Why use the V+ Text to Speech Device?

There are two advantages to using the V+ Text to Speech (TTS) device. The first is better speech quality. The second is the ability to change the speech output in real time, without stopping the program.

Better Speech Quality

Current TTS systems have some common shortcomings: the speech often sounds unnatural because the rhythm, intonation and phonetic details are poor. As a result, listening to such speech requires a greater cognitive effort. V+ uses control tags to improve the prosody of text-to-speech translation, making it easier to understand the speech.

Speech Output Changes in Real-time

V+ uses two methods for changing speech output in real-time: dynamic text and dynamic template filenames.

  • Dynamic text uses port input values to "change speech output from within a text file."

  • Dynamic template filenames use port input values to "change speech output by switching text template files."

Both of these methods are performed during run-time. These features can be combined to allow almost unlimited real-time speech output possibilities.

Note that you must first download and install V+ and all necessary supporting software before using this product.
