Problems solved by technology

However, due to the limitations of hardware technology, the existing products cannot update and solidify the voice dialogue content stored in the hardware. The capacity is limited, and the number of words for voice recognition is also limited, generally 6 to 10 words. The recognition effect is not good, the recognition rate is low, and its interaction methods, occasions, reliability, and updateability are greatly restricted, which makes this technology unable to be widely used
[0003] For example, there is an existing voice interactive toy whose sound signal is an anthropomorphic signal and the content of the dialogue is the voice content solidified in the device. When the user is a child, it is difficult for the user to accept the anthropomorphic sound, and the There is also the problem of not being able to freely and timely change the dialogue content used in the interaction. After a period of use, the user loses the sense of freshness, thus reducing the interest. At the same time, the user's design ability cannot be brought into play, and the user cannot customize its personalized interactive content and pronunciation.

Embodiment 1

[0057] Such as figure 1 As shown, the present embodiment provides a voice intelligent system for smart toys, which can be applied to various voice platforms to realize voice interaction, such as voice intelligent toys, robots, man-machine dialogue systems, etc., the specific structure is as follows figure 1 shown, including:

[0058] The processor, memory, voice processing unit and communication processing unit are all arranged on the circuit board, and the memory, voice processing unit and communication processing unit are connected to the processor through the bus to form an embedded control board;

[0059] Voice input device, voice output device are respectively connected with the described voice processing unit on the embedded control board;

[0060] The communication processing unit is provided with a communication interface, and the communication interface is connected to a computer installed with custom client software.

[0061] Wherein, the memory includes: a dynamic...

Embodiment 2

[0069] This embodiment provides an interactive method based on the voice intelligence system of the smart toy in Embodiment 1, the method comprising:

[0070] After the system starts, through the control of the processor, the speech recognition module and the speech library module stored in the FLASH memory are loaded into the dynamic memory. In practice, these two modules are in the form of software, such as speech recognition based on HMM engine;

[0071] The external voice command is entered by the voice input device, and the analog voice signal of the external voice command is converted into a digital voice signal by a voice processing unit (such as by a voice acquisition chip in the voice processing unit);

[0072] The digital sound signal is sent to the processor, and the processor calls the speech recognition module in the dynamic memory simultaneously, and compares the pronunciation characteristics of the speech pronunciation feature library in the speech recognition e...

Embodiment 3

[0093] In this embodiment, the intelligent voice system and its interaction method of the present invention are further described through a specific implementation process, such as Figure 6-13 As shown, the system is divided into two aspects: software and hardware, including:

[0094] (1) Hardware part:

[0095] The hardware is based on the ARM9 high-performance SOC processor S3C2410, the main frequency is 200Mhz, and the ARM9 SC2410 embedded controller is the center, through the external microphone sensor to complete the collection of voice signals, the sampling, amplification and pre-filtering of voice signals and the subsequent voice The playback is completed by the audio chip WM8731. The board is equipped with 32×16bit extended SDRAM storage space and 64M×16bit NAND Flash storage space. The system uses the USB interface to communicate with the client interface of the user application development layer. In this system, the USB interface is taken as an example to illustrat...

Description

technical field [0001] The invention relates to the technical field of intelligent voice control, in particular to an intelligent voice interaction system and an interaction method with an embedded structure. Background technique [0002] At present, consumer electronic products based on speech processing technology are very popular in the market, and there are many kinds of interactive products, but most of these products are based on dedicated speech recognition chips, and their cores are single-chip microcomputers or digital signal central processing units. It is to sample and encode the sound signal input by the microphone, and then match it with the pre-recorded voice information through the internal processor, and then output the corresponding voice information through the on-chip module through the external speaker. However, due to the limitations of hardware technology, the existing products cannot update and solidify the voice dialogue content stored in the hardware...
