VoiceTextTM Text-To-Speech (TTS) Engine
VoiceText™ Text-To-Speech Engine is the core software component that generates synthesized speech from a given input text. Generally, VoiceText™ Text-To-Speech Engine is used for building custom stand-alone applications such as desktop applications, navigation systems, etc. However, it can also be used simply to output speech from an input text using the provided desktop TTS program.
Natural Sound and Clear Pronunciation
VoiceText™ Text-To-Speech Engine provides very natural and highly intelligible output.
With variable footprints ranging from 16 to over 600 megabytes, VoiceText™ is configurable for use in a wide range of desktop applications.
Multiple Languages, Multiple Voices
VoiceText™ is available as US English TTS, Latin American Spanish TTS, Korean TTS, Japanese TTS and Mandarin Chinese TTS. A collection of eleven native voices is available across these languages.
Large Extensible Dictionary
Hundreds of thousands of pronunciations are included in the default dictionary of each of the supported languages. VoiceText™ also supports customization of the dictionary so that developers can adjust pronunciations of symbols, abbreviations, and new terms.
Pitch, speed, volume, and pauses can be customized, both dynamically and by global setting. VoiceText Markup Language (VTML) is provided for inline customization.
Pre-Processing of Input Text
VoiceText™ automatically handles special input such as dates, times, abbreviations found in addresses, and sentences with mixed languages.
Flexible Data Output Formats
VoiceText™ Text-To-Speech Engine currently supports the following formats in 8KHz, 11KHz, and 16KHz sampling rates:
16bit linear PCM
8bit A-law PCM
8bit Mu-law PCM
4bit Dialogic ADPCM
16bit linear PCM Wave
