E-Speech offers two types of speech output systems: custom-developed speech generation systems and general purpose, full-featured text-to-speech. (Scroll down for demos of the custom systems). We also offer name pronunciation software, and text preprocessing software.

General Purpose Text-to-Speech Synthesis

E-Speech offers a small footprint text-to-speech system for American English.

The system has a total footprint of under 5MB, of which the phoneme-to-sound component is less than 2MB. This system excels at pronouncing names and addresses, at producing speech of high intelligibility,  and at performing the kinds of text normalization needed for many database and information-based applications.  For these reasons, they are ideal for many telephony applications.  Listen to some of the sample applications below, or contact us to find out how E-Speech synthesis can help with your applications.

Lists of People's Names

Because of its superior name pronunciation accuracy and segmental intelligibility, the E-Speech synthesizer is ideal for speaking lists of names. For example, a list of local doctors participating in a health plan:

Neurologists in the Oswego area:
Enrique M. Vasquez
John Athanasios
Ehrhard Breneman
Aaron Narayan
Evelyne Glendenning
Louis Migliaccio
Jocelyn Dlugosz
John Szymanski

Twyla Goeke
Malcolm Deleeuw
Shih Hsin Liu

Driving Directions and Traffic Reports

Because E-Speech software is excellent at pronouncing the names of geographical locations, including street and town names, it is ideally suited to speaking driving directions or traffic reports. For example, in combination with our text preprocessors for traffic newsfeeds, it can provide speech output for traffic reports.

Thursday Traffic Report from SCOUT: Report_time: 16:06 Detail: (10:39) IN UNION COUNTY: ON THE ROUTE 78 LOCAL LANES, THE RIGHT LANES ARE CLOSED BOTH WAYS BETWEEN VAUXHALL ROAD AND THE GARDEN STATE PARKWAY. Report_time: 15:45 Detail: INBOUND G.W.B. MINOR. INBOUND LINCOLN TUNNEL AND HOLLAND TUNNEL MINOR. (listen)

Or it can be used for driving directions:

The nearest restaurant on Massachusetts Avenue in Harvard Square to the Hyatt Regency is the Hong Kong. I'll try to find the best way to get there. If you are on the opposite side of the street from the Hyatt Regency, follow the traffic. Bear left at the fork. After you pass Flagg Street on the right, take the next right onto DeWolf Street. After you cross Mt Auburn Street, make an easy right onto Bow Street. After you pass Arrow Street on the right, make the first hard right onto Massachusetts Avenue. The Hong Kong is about twenty yards down on your right side. That's the end of the directions. (listen)

Stock Market Reports

E-Speech software is excellent for speech recognition or synthesis for stock applications. For example, it pronounces the names of most Nasdaq companies accurately, and because our letter-to-phoneme software is rule-based, it can accurately pronounce names of many new companies. For example:

Athena
Centillium
Cholestech
Easylink
Plumtree
Kyphon
Synaptics
Viacell
Virologic

Email

Our email preprocessor converts email format into a text format that is more appropriate for speech synthesis.

Custom Speech Generation Systems

See our Custom Products page for illustrations of our special-purpose speech generation systems.

Latin-American Spanish Name Synthesis System

Our Latin-American Spanish synthesis system speaks people's names based on E-Speech's proprietary subword concatenation algorithms. The system converts orthography to phonemes and stress marks and then generates speech from its sound inventory.  Here are some examples:

Jose Rodriguez
Juan Rosario Cardenas
Miguel Cruz Gonzalez
Pilar Estella Echevarria
Olivia deJesus Corrales
(listen)

The system can accommodate either text written in conventional Spanish orthography in 8-bit ASCII or text written in 7-bit ASCII without accents.  The system is currently based on a sound inventory that produces excellent or good quality speech for names of almost 90% of people, but it is expandable in inventory size, if equivalent quality is required for more names. It is based on the algorithms described in our Custom Products page.
