Open vocabulary speech recognition
First Claim
1. A method for open vocabulary speech recognition performed by an electronic device, the method comprising:
- receiving an utterance waveform;
processing the waveform to provide feature vectors representing the waveform;
comparing the feature vectors with concatenated isolated word acoustic models from a concatenated isolated word acoustic model list to select a suitable concatenated isolated word acoustic model; and
providing a response depending on the suitable concatenated isolated word acoustic model.

Abstract
There is described a method 300 for open vocabulary speech recognition performed by an electronic device (100). The method (300) includes receiving an utterance waveform (320) and Processing the waveform (350) to provide feature vectors representing the waveform. Then a step of comparing (360) is effected, the comparing compares the feature vectors with concatenated isolated word acoustic models from a concatenated isolated word acoustic model list to select a suitable concatenated isolated word acoustic model. Then a providing a response step (370) provides a response depending on the suitable concatenated isolated word acoustic model. The response typically is a control signal for activating a function of the device (100).
