Embodiment Construction

[0015] The present invention is applicable to any telecommunication system comprising an electronic device containing a speech recognition application and a server between which data can be communicated. Hereinafter, the description uses a phoneme sequence as a pronunciation model, however, the present invention is not limited thereto.

[0016] Figure 1a Several different examples are shown where the invention can be applied. An electronic device TE connected to a local area network LAN includes data transmission means and software controlling data transmission in order to communicate with devices in the network LAN. The TE may comprise a network interface card for a wireless local area network, which is based on one of the IEEE.11 standards or on the standards of the BRAN (Broadband Radio Access Network) standardization project. The electronic equipment TE can be connected to a local area network LAN and further connected to a server S through an access point AP or through ...

Abstract

A method needed in speech recognition for forming a pronunciation model in a telecommunications system comprising at least one portable electronic device and server. The electronic device is arranged to compare the user's speech information with pronunciation models comprising acoustic units and stored in the electronic device. A character sequence is transferred from the electronic device to the server. In the server, the character device is converted into a sequence of acoustic units. A sequence of acoustic units is sent from the server to the electronic device. <IMAGE>

Description

technical field [0001] The present invention relates to speaker-independent speech recognition in telecommunication systems, and more particularly to pronunciation modeling for speech recognition. technical background [0002] Different speech recognition applications have been developed in recent years, eg user interfaces for automobiles and mobile stations etc. Known methods for mobile stations include calling a specific person by speaking his / her name aloud into the mobile station's microphone and setting up a call to a number based on the name spoken by the user. However, the method generally requires training of mobile stations or systems in the network in order to recognize the pronunciation of each name. Speaker-independent voice recognition improves the usability of voice-controlled user interfaces, since this training phase can be omitted. In speaker-independent name selection, the pronunciation of the names in the contact information can be modeled, and the name ...
