چکیده

We present a novel hardware device that combines a regular microphone with a bone-conductive microphone. The device looks like a regular headset and it can be plugged into any machine with a USB port. The bone-conductive microphone has an interesting property: it is insensitive to ambient noise and captures the low frequency portion of the speech signals. Thanks to the signals from the boneconductive microphone, we are able to detect very robustly whether the speaker is talking, eliminating more than 90% of background speech. Furthermore, by combining both channels, we are able to significantly remove background speech even when the background speaker speaks at the same time as the speaker wearing the headset.

Combination method of bone-conduction speech and air-conduction speech for speaker recognition

Recently, some new sensors, such as bone-conductive microphones, throat microphones, and non-audible murmur (NAM) microphones, besides conventional condenser microphones have been developed for collecting speech data. Accordingly, some researchers began to study speaker and speech recognition using speech data collected by these new sensors. We focus on bone-conduction speech data collected by ...

A graphical model for multi-sensory speech processing in air-and-bone conductive microphones

In continuation of our previous work on using an air-and-boneconductive microphone for speech enhancement, in this paper we propose a graphical model based approach to estimating the clean speech signal given the noisy observations in the air sensor. We also show how the same model can be used as a speech/non-speech classifier. With the aid of MOS (mean opinion score) tests we show, that the pe...

Signal processing techniques for seat belt microphone arrays

Microphones integrated on a seat belt are an interesting alternative to conventional sensor positions used for handsfree telephony or speech dialog systems in automobile environments. In the setup presented in this contribution, the seat belt consists of three microphones which usually lay around the shoulder and chest of a sitting passenger. The main benefit of belt microphones is the small di...

شکل‌دهی وفقی و هوشمند پرتو در آرایه‌های میکروفونی Ad-hoc با استفاده از خوشه‌بندی و رتبه‌بندی میکروفون‌ها

Considering the existence of a many speech degradation factors, speech enhancement has become an important topic in the field of speech processing. Beamforming is one of the well-known methods for improving the speech quality that is conventionally applied using regular (classical) microphone arrays. Due to the restrictions in the regular arrangement of microphones, in recent years there has be...

Towards Robust Speech Acquisition using Sensor Arrays

An integrated system approach was developed to address the problem of distant speech acquisition in multi-party meetings, using multiple microphones and cameras. Microphone array processing techniques have presented a potential alternative to close-talking microphones by providing speech enhancement through spatial filtering and directional discrimination. These techniques relied on accurate sp...
