Personal sound allows individuals, or small groups of individuals, to listen to separate streams of audio content without external interruption from a third-party. The experience and utility of personal sound is a highly sought after characteristic of shared spaces. A prototype system implementation using DSPs is also planned. We plan to investigate further to improve prediction accuracy using prediction coefficient extrapolation. It was found that (1) speech cancellation of up to about 10 dB is possible, but is highly speaker dependent, (2) secondary loud speaker should be oriented in the same direction as the primary source, i.e., the mouth. We then actually played out both the original and the predicted samples simultaneously from two loud speakers. Predicted samples of recorded speech was first prepared off line. At a sampling frequency of 8 kHz, speech emission control of about 7 dB for female speech and 4 dB for male speech was found to be possible.įinally, we experimentally evaluated the proposed active speech control method. Lowering the sampling frequency in order to lower the number of predicted samples at the cost of reduced bandwidth further enhances prediction accuracy.

The prediction coefficient update is suppressed during this recursion. However, the prediction must also cover the long delay associated with the acoustic to/from electric conversion, as well as A/D, D/A conversions, and all associated processing, which we found could go up to as long as 3 ms.īy using LPC predicted samples recursively to predict further samples, we found that prediction with SNR of about 6 dB is possible, even with this long delay. We first show that speech cancellation is possible with a secondary source placed in proximity to the mouth generating linear-predicted phase-inverted speech. Both of these applications do not require speech to be radiated into surrounding space, but only into the input microphone, and would benefit if global radiation is controlled. Some examples of the intended application of this system are cellular speech cancellation and speech input for recognition-based dictation systems.

We are constantly optimizing and improving our text to speech conversion services and In order to maintain this software we collect and leverage usage data.We investigated on the possibility of an active cancellation system for unnecessary speech radiation control.
