| 20100106507 | Ratio of Speech to Non-Speech Audio such as for Elderly or Hearing-Impaired Listeners - The invention relates to audio signal processing and speech enhancement. In accordance with one aspect, the invention combines a high-quality audio program that is a mix of speech and non-speech audio with a lower-quality copy of the speech components contained in the audio program for the purpose of generating a high-quality audio program with an increased ratio of speech to non-speech audio such as may benefit the elderly, hearing impaired or other listeners. Aspects of the invention are particularly useful for television and home theater sound, although they may be applicable to other audio and sound applications. The invention relates to methods, apparatus for performing such methods, and to software stored on a computer-readable medium for causing a computer to perform such methods. | 04-29-2010 |
| 20100121634 | Speech Enhancement in Entertainment Audio - The invention relates to audio signal processing. More specifically, the invention relates to enhancing entertainment audio, such as television audio, to improve the clarity and intelligibility of speech, such as dialog and narrative audio. The invention relates to methods, apparatus for performing such methods, and to software stored on a computer-readable medium for causing a computer to perform such methods. | 05-13-2010 |
| 20110054887 | Method and Apparatus for Maintaining Speech Audibility in Multi-Channel Audio with Minimal Impact on Surround Experience - In one embodiment the present invention includes a method of improving audibility of speech in a multi-channel audio signal. The method includes comparing a first characteristic and a second characteristic of the multi-channel audio signal to generate an attenuation factor. The first characteristic corresponds to a first channel of the multi-channel audio signal that contains speech and non-speech audio, and the second characteristic corresponds to a second channel of the multi-channel audio signal that contains predominantly non-speech audio. The method further includes adjusting the attenuation factor according to a speech likelihood value to generate an adjusted attenuation factor. The method further includes attenuating the second channel using the adjusted attenuation factor. | 03-03-2011 |
| 20110082575 | Concealing Audio Artifacts - At least one segment is identified in an audio signal. The audio segment is associated with an artifact within the audio signal and has a time duration. At least one stored sound clip is retrieved, which has a time duration that exceeds the time duration associated with the audio segment. The retrieved sound clip is mixed with the audio signal and the retrieved sound clip audibly compensates for the audio artifact. | 04-07-2011 |
