Text to Speech Module
  • Text-to-Speech [TTS] technology is defined as a computer system's ability to translate text into synthesized speech.
  • Today's deployment of TTS can be divided into three segments: enterprise and telecommunications / automotive and mobile / consumer applications.
  • A Large TTS footprint is host or server-based, accessed by multiple remote clients, and a small footprint is embedded. TTS is ideal for high-volume enterprise and telecommunications speech services.
  • By now, most businesses are familiar with TTS technology enhancing the way mobile workers access and respond to information on a daily basis.
  • Sales and field staff can be notified immediately of important e-mails and access all their messages from any standard mobile or fixed line telephone.
  • Companies such as IBM®, Microsoft®, and Cisco® already use TTS technology for their mobile workforce.
IVR and Telephony Systems

In server applications, TTS is used to generate dynamic text for any situation where pre-recorded speech is cumbersome or impossible. Examples of TTS working in server applications include:

  • Reading email messages
  • Address data
  • Names
  • Part numbers
  • Financial information, including account balances and stock prices, etc.
  • Alerts (e.g. reminder to take a prescription drug)

The most powerful argument for using TTS technology in the telecom world is the advantage of reducing costs and expediting development by supplanting human recordings. By using TTS prompts, an organization can reduce staffing requirements while improving the speed and quality of customer service. In some cases, the TTS supports scores of languages that would otherwise be unavailable using a person. TTS in the telecom space is widespread and varied. TTS allows flexible data to be output from any content source, like databases and the Internet, on demand. Market leaders for voice, video, and data convergence over broadband networks have licensed TTS for a variety of applications that provide businesses with innovative ways to manage information and resources. Users may improve their productivity by being able to access voice mail, fax and email from one central location.

Unified messaging is now defined primarily as "e-mail by phone.” Esna Technologies’ Telephony Office-LinX™ Unified Communication platforms all incorporate a large footprint, flexible TTS system. This system allows people to receive their e-mail messages over the phone.

TTS technology is used most effectively to scan e-mail message content for high importance or urgency. Responses can then be made by phone, rather than by more cumbersome and time-consuming (login, password, internet connection down, etc.) e-mail. Despite the decade-long availability of competent algorithms to ‘normalize’ the text of e-mail headers, top TTS systems still perform poorly, reading headers character-by-character. This is especially dire in the "Reply" and "Forward" functions. This is the main reason Esna Technologies invested in offering RealSpeak TTS in their solution, as it is by far the market leader in quality and accuracy.
