Abstract

A device, system, and method whereby a speech-driven system can distinguish speech obtained from users of the system from other speech spoken by background persons, as well as from background speech from public address systems. In one aspect, the present system and method prepares, in advance of field-use, a voice-data file which is created in a training environment. The training environment exhibits both desired user speech and unwanted background speech, including unwanted speech from persons other than a user and also speech from a PA system. The speech recognition system is trained or otherwise programmed to identify wanted user speech which may be spoken concurrently with the background sounds. In an embodiment, during the pre-field-use phase the training or programming may be accomplished by having persons who are training listeners audit the pre-recorded sounds to identify the desired user speech. A processor-based learning system is trained to duplicate the assessments made by the human listeners.

Claims (43)

1. A method of speech recognition for use in warehouse picking operations, the method comprising:

receiving, at a microphone of a speech cognition device (SRD), an audio input, wherein the audio input is related to a confirmation phrase uttered in response to an instruction to pick an item;

identifying, via a hardware processor of the SRD communicatively coupled with the microphone, a vocalization in the received audio input;

classifying, via the hardware processor, a portion of the identified vocalization based on a machine learning model trained to understand input natural language, wherein the portion of the identified vocalization is classified as at least one of a user speech or a background speech;

in an instance in which the portion of the identified vocalization is classified as the user speech;

processing, via the hardware processor the portion of the identified vocalization. and

generating, via the hardware processor, at least one of words or phrases related to the warehouse picking operations, and

in an instance in which the portion of the identified vocalization is classified as the background speech, filtering via the hardware processor the portion of the identified vocalization.

2. The method of claim 1 , wherein the machine learning model is at least one of a neural network system, a support vector machine, or an inductive logic system.

3. The method of claim 1 , wherein the confirmation phrase is at least one of a confirmation of a recognition of a prompt, a confirmation of a completion of a task, or a confirmation of an identification of at least of a location and an object.

4. The method of claim 1 , wherein the microphone is mounted on a headset and is configured for use in a warehouse environment.

5. The method of claim 1 , wherein the machine learning model is trained based on a training corpus comprising at least one word or phrase related to the warehouse picking operations.

6. The method of claim 5 , wherein the machine learning model is trained based on the training corpus and the audio input received during the warehouse picking operations.

7. A speech recognition device (SRD) for use in warehouse picking operations comprising:

a microphone;

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the SRD to at least:

receive, at the microphone of the SRD, an audio input, wherein the audio input is related to a confirmation phrase uttered in response to an instruction to pick an item;

identify a vocalization in the received audio input;

classify a portion of the identified vocalization based on a machine learning model trained to understand input natural language, wherein the portion of the identified vocalization is classified as at least one of a user speech or a background speech;

in an instance in which the portion of the identified vocalization is classified as the user speech;

process the portion of the identified vocalization, and

generate at least one of words or phrases related to the warehouse picking operations; and

in an instance in which the portion of the identified vocalization is classified as the background speech, filter the portion of the identified vocalization.

8. The SRD of claim 7 , wherein the machine learning model is at least one of a neural network system, a support vector machine, or an inductive logic system and wherein the machine learning model is trained to distinguish the user speech from the background speech.

9. The SRD of claim 7 , wherein the confirmation phrase is at least one of a confirmation of a recognition of a prompt, a confirmation of a completion of a task, or a confirmation of an identification of at least of a location and an object.

10. The SRD of claim 7 , further comprising a headset, wherein the microphone is mounted on the headset and is configured for use in a warehouse environment.

11. The SRD of claim 7 , wherein the machine learning model is trained based on a training corpus comprising at least one word or phrase related to the warehouse picking operations.

12. The SRD of claim 11 , wherein the machine learning model is trained based on the training corpus and the audio input received during the warehouse picking operations.

13. A method of speech recognition for use in warehouse picking operations, the method comprising:

receiving, at a microphone of a speech recognition device (SRD), an audio input, wherein at least a portion of the audio input is related to a confirmation phrase uttered in response to an instruction to pick an item;

identifying, via a hardware processor of the SRD communicatively coupled with the microphone, a vocalization in the received audio input;

classifying, via the hardware processor, the portion of the identified vocalization based on a machine learning model trained to understand input natural language, wherein the portion of the identified vocalization is classified as at least one of a user speech, an environmental noise, or a background speech;

in an instance in which the portion of the identified vocalization is classified as the user speech;

processing, via the hardware processor, the portion of the identified vocalization. and

generating, via the hardware processor, at least one of words or phrases related to the warehouse picking operations;

in an instance in which the portion of the identified vocalization is classified as the background speech, filtering, via the hardware processor, the portion of the identified vocalization; and

in an instance in which the portion of the identified vocalization is classified as the environmental noise, filtering, via the hardware processor, the portion of the identified vocalization.

14. The method of claim 13 , wherein the machine learning model is at least one of a neural network system, a support vector machine, or an inductive logic system.

15. The method of claim 13 , wherein the confirmation phrase is at least one of a confirmation of a recognition of a prompt, a confirmation of a completion of a task, or a confirmation of an identification of at least of a location and an object.

16. The method of claim 13 , wherein the microphone is mounted on a headset and is configured for use in a warehouse environment.

17. The method of claim 13 , wherein the environmental noise comprises at least one of an operation of a vehicle in a warehouse or a movement of pallets in the warehouse.

18. The method of claim 13 , wherein the machine learning model is trained based on a training corpus comprising at least one word or phrase related to the warehouse picking operations.
