NAVTEQ has announced the availability of voice phonemes for its NAVTEQ map for Mexico and NAVTEQ map for Puerto Rico. This content greatly enhances navigation system functionality for these countries by enabling navigation systems using NAVTEQ data to provide audible guidance using specific street names and administrative areas, as well as the ability to provide speech recognition.
For example, many navigation systems provide generic, audible directions such as “turn right” or “stay to the left.” With the integration of voice phonemes into the NAVTEQ map, navigation systems can offer the correct pronunciation of specific spoken directions such as turn left onto Luis Moya Avenue.
Additionally, end-users using a navigation system enabled with NAVTEQ Voice are now able to select their destination by speaking the name of that target into the navigation system, rather than entering it manually.
NAVTEQ employs a unique method of transcribing the voice data that includes manually checking all transcriptions. The end result is highly accurate data that can interpret abbreviations, alternate pronunciations and other variants.
For example in Spanish the letter “S” can represent SAN, the letter “D” DOCTOR, or the string NTRA can represent NUESTRA. Contextual variants are even taken into account. For example J.M. can represent both Jose Maria and Jose Manuel.
Local geographic analysts are extremely important for interpreting local pronunciations. In European (Castillian) Spanish the word ‘plaza’ is pronounced like ‘plath-a’, while in Latin American Spanish, it is pronounced like ‘plas-a.’ Additionally, the product sets a preference for names that can be pronounced in several ways.
The NAVTEQ Map for Mexico contains phonemes for over 180,000 street names and over 25,000 administrative areas. The NAVTEQ Map for Puerto Rico contains approximately 14,500 street names and over 2,600 administrative areas.
