Embodiment Construction

[0013] The following description of preferred embodiments is merely exemplary in nature and is not intended to constitute a limitation of the invention, its application or uses.

[0014] Such as figure 1 As shown, at step 12, the user speaks the name of a contact, thereby triggering the voice dialing algorithm 10. Voice dialing system 10 interprets the entered contact name and associates the entered contact name with a contact name in the address book. At step 14, voice dialing system 10 determines a confidence measure for the entered contact name. In step 16, the voice dialing system determines whether the confidence measure is greater than a threshold. If the confidence measure is greater than the threshold, the voice dialing system 10 obtains the contact's phone number according to the contact's name in step 18 and dials out. For example, voice dialing system 10 may require the confidence measure to be greater than a certain threshold, such as 60%. This threshold can be...

Abstract

A method for improving recognition results of a speech recognizer uses supplementary information to confirm recognition results. A user inputs speech to a speech recognizer residing on a mobile device or on a server at a remote location. The speech recognizer determines a recognition result based on the input speech. A confidence measure is calculated for the recognition result. If the confidence measure is below a threshold, the user is prompted for supplementary data. The supplementary data is determined dynamically based on ambiguities between the input speech and the recognition result; the supplementary data distinguishes the input speech over potential incorrect results. The supplementary data may be a subset of alphanumeric characters that comprise the input speech, or other data associated with a desired result, such as an area code or location. The user may provide the supplementary data verbally, or manually using a keypad, touchpad, touchscreen, or stylus pen.

Description

technical field [0001] The invention relates to a voice dialing system, in particular to improving the performance of the voice dialing system. Background technique [0002] Voice dialing systems require voice recognition capabilities to process voice commands. On mobile phones, users can easily dial a phone number using speech recognition technology. For example, a user can initiate a call to a contact by speaking the name of the contact in the mobile phone's address book. The voice dialing system processes the name through voice recognition technology and automatically dials the correct number. [0003] In order for the voice dialing system to correctly identify the phone number to dial, the user must clearly speak the contact's name. However, voice distortion, mispronunciation, and background noise, for example, can cause the voice dialing system to misinterpret the intended contact. Thus, the voice dialing system can implement a system in which a user's input voice i...
