Embodiment 1

[0046] see figure 1 , which is a flow chart of the method for multi-device cooperative interaction in Embodiment 1. Embodiment 1 of the present invention provides a method for multi-device cooperative interaction, which is applied in the cloud, and includes the following steps:

[0047] S110: receiving step, receiving the same voice request information sent by multiple terminal devices, and extracting the wake-up words marked in the voice request information.

[0048] When the user sends out voice information, if multiple device terminals receive it at the same time, the multiple device terminals will upload the received voice information to the cloud. At the same time, when the device terminal uploads a voice request, it will mark the wake-up word. For example: when the voice message sent by the user is "Xiaodu Xiaodu, turn on the device", if several devices receive the voice message at the same time, the wake-up word "Xiaodu Xiaodu" will be marked first, and then the recei...

Embodiment 2

[0061] The difference from Embodiment 1 is that Embodiment 2 further includes a calibration step for calibrating the recording capabilities of multiple terminal devices. Since different terminal devices have different recording capabilities, the recording capabilities need to be calibrated. The specific plan is as follows:

[0062] Such as image 3 As shown in FIG. 2 , it is a flow chart of the method for multi-device cooperative interaction in the second embodiment. Embodiment 2 of the present invention provides a method for collaborative interaction of multiple devices, including the following steps:

[0063] S210: Calibration step, calibrating the recording capabilities of multiple terminal devices; the calibration step S210 specifically includes:

[0064] Send the playing request of the voice information to multiple terminal devices, and the multiple terminal devices play the voice information and record it at the same time.

[0065] The recording information uploaded ...

Embodiment 3

[0073] Compared with the second embodiment, the third embodiment also adds a setting step for adding or deleting terminal devices by the user. The specific plan is as follows:

[0074] see Figure 4 , which is a flow chart of the steps of the method for multi-device cooperative interaction in Embodiment 3. Embodiment 3 provides a method for multi-device collaborative interaction, which specifically includes:

[0075] S310: a setting step, adding or deleting terminal devices to be used.

[0076] In this step, the user adds and deletes devices according to specific scenarios and usage requirements. For example, the user may only need to add several terminal devices that are close to each other, such as TVs and speakers. Because terminal devices located close to each other are easier to receive the same voice information at the same time.

[0077] S320: a calibration step, calibrating the recording capabilities of multiple terminal devices; the calibration step S320 specific...

Abstract

The invention provides a multi-device interaction cooperative method comprising the following steps: a reception step of receiving same voice request information sent by a plurality of terminal devices; an identification step of identifying the voices of the received voice request information; a computing step that calculates the energy values of an awakening word in the voice request information;a feedback step that compares the sizes of the energy values of the awakening word, and respectively sends feedback information to the terminal devices according to the energy value comparison results and voice identification results. The method can calculate the energy values of the awakening word in the voice requests sent by different terminal devices, thus distinguishing the distances betweeneach terminal device and the speaker; only the terminal device with the closest distance from the speaker can respond to the user request, thus ensuring the response uniqueness, and ensuring the userexperiences.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, and in particular to a method and device, device and computer-readable medium for multi-device interaction and collaboration. Background technique [0002] With the rise of intelligent voice interactive devices, more and more occasions have more than one intelligent voice device. For example: In the use scene of smart home, there are multiple devices such as TV, refrigerator, and speaker. Each device needs to use the wake-up word to wake up, and if the wake-up words of the devices are the same, for example: when the user uses the wake-up word "Xiaodu Xiaodu" to wake up, these awakened devices will respond to the speaker's request at the same time, while interacting with the user. At this time, it will cause confusion to the user, who does not know which device to perform voice interaction with. Contents of the invention [0003] Embodiments of the present invention provide...
