Abstract

Apparatus, including a sensor which is configured to be fixed to a neck of an operator of equipment in a location suitable for sensing a voiceless alaryngeal speech vibration generated by the operator during operation of the equipment, The apparatus further includes a processor which is configured to receive and process a signal output by the sensor so as to measure the voiceless alaryngeal speech vibration and so as to generate a control signal for the equipment responsively to the measured voiceless alaryngeal speech vibration.

First claim

I claim:

1. Apparatus for eliminating muffled speech caused by a physician's mask used by an operator during a medical procedure, comprising:
a probe configured to be inserted into a patient's body by the operator, the probe being configured to be used by the operator for performing the medical procedure in the patient's body;
a sensor, adapted to be fixed to a neck of an operator of equipment and configured for sensing a voiceless alaryngeal speech vibration generated by the operator during operation of the equipment;
a screen for displaying one or more graphic user interfaces while the probe is being used by the operator in the patient's body and providing feedback to the operator during the medical procedure;
a processor, configured to receive and process a signal output by the sensor during mouthing of muffled speech through the physician mask by the operator so as to measure the voiceless alaryngeal speech vibration and so as to generate a control signal indicative of a particular action to be taken by the equipment using the probe responsively to the measured voiceless alaryngeal speech vibration during the medical procedure, the particular action to be taken with the probe in the patient's body being verified by displaying a query on the screen for the operator to confirm using the one or more graphic user interfaces.

2. The apparatus according to claim 1 , wherein the voiceless alaryngeal speech vibration comprise a group of different voiceless alaryngeal sound vibrations generated by the operator, and wherein measuring the voiceless alaryngeal speech vibration comprises distinguishing the voiceless alaryngeal sound vibrations within the group.

3. The apparatus according to claim 1 , wherein the voiceless alaryngeal speech vibration comprises a group of different voiceless alaryngeal sound vibrations generated by the operator, and wherein the processor is configured to store one-to-one correspondences between the group of different voiceless alaryngeal sound vibrations and a set of different control signals for the equipment selected by the operator.

4. The apparatus according to claim 1 , wherein the equipment is configured to perform ablation on a heart of a patient.

5. The apparatus according to claim 1 , wherein the sensor comprises an electromyographically controlled electrolarynx (EMG-EL).

6. A method for eliminating muffled speech caused by a physician's mask used by an operator conducting a medical procedure, comprising the steps of:
providing a probe configured to be inserted into a patient's body by the operator, the probe being configured to be used by the operator for performing the medical procedure in the patient's body;
fixing a sensor to a neck of an operator of equipment, the sensor being configured for sensing a voiceless alaryngeal speech vibration generated by the operator during operation of the equipment;
displaying one or more graphic user interfaces on a screen while the probe is being used by the operator in the patient's body and providing feedback to the operator during the medical procedure;
receiving and processing a signal output by the sensor during mouthing of muffled speech through the physician mask by the operator so as to measure the voiceless alaryngeal speech vibration and so as to generate a control signal indicative of a particular action to be taken by the equipment using the probe responsively to the measured voiceless alaryngeal speech vibration during the medical procedure; and
verifying the particular action to be taken with the probe in the patient's body by displaying a query on the screen for the operator to confirm using the one or more graphic user interfaces.

7. The method according to claim 6 , wherein the voiceless alaryngeal speech vibration comprises a group of different voiceless alaryngeal sound vibrations generated by the operator, and wherein measuring the voiceless alaryngeal speech vibration comprises distinguishing the voiceless alaryngeal sound vibrations within the group.

8. The method according to claim 6 , wherein the voiceless alaryngeal speech vibration comprises a group of different voiceless alaryngeal sound vibrations generated by the operator, the method further comprising storing one-to-one correspondences between the group of different voiceless alaryngeal sound vibrations and a set of different control signals for the equipment selected by the operator.

9. The method according to claim 6 , wherein the equipment is configured to perform ablation on a heart of a patient.

10. The method according to claim 6 , wherein the sensor comprises an electromyographically controlled electrolarynx (EMG-EL).
