| In principle, any input transducer may be used, but the simplest is the one that is already there: the microphone. | |
13 Citations | To enhance the quality of speech in a hands–free telecommunication environment, microphone arrays consisting of multiple microphones can be used for sound pick–up. |
12 May 1998 18 Citations | A microphone array is a promising solution for realizing hands-free speech recognition in real environments. |
| Traditional classic microphones should be near the speaker either by wearing the microphone or by using movable microphone. | |
24 May 2009 | The advantage of the proposed algorithm is that it requires no calibration of microphone arrays. |
07 Nov 2011 | The mechanism provides a general design principle for unidirectional mechanical amplification that we have also employed to construct an active microphone. |
| The proposed microphone array responds well to these requirements under realistic conditions. | |
| It will be shown that in order to increase the signal to noise ratio it is favourable to integrate the preamplifier with the microphone, which implies that the microphone should be made of silicon, preferably with a single wafer technology. | |
12 May 2008 37 Citations | Experimental results demonstrate the beneficial use of the new single microphone system that reduces echo and coloration with little speech distortion. |
66 Citations | A microphone array has the potential for surmounting both of these problems. |
09 Jun 2003 15 Citations | Spectral subtraction is an effective method to reduce stationary additive noise from a single microphone signal. |
97 Citations | The experimental results proved that the corrugation technique is promising for silicon condenser microphone. |
55 Citations | The results show that a more stable solution is obtained with the proposed two microphone approach. |
19 Apr 2015 | Results show that a speech signal with extended bandwidth and high signal-to-noise ratio may be achieved using the available microphone signals. |
| Moreover, the corrugation technique makes it possible to integrate easily the electric circuits on the single chip that contains the microphone. | |
8 Citations | By viewing the microphone-amplifier system together, we develop a different method of optimization, leading to lower noise. |
