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

Example Embodiment

[0056] Example one

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

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

[0059] The voice input device and the voice output device are respectively connected to the 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 with a computer on which the customized client software is installed.

Example Embodiment

[0068] Example two

[0069] This embodiment provides an interaction method based on the voice intelligent system of the smart toy in the first embodiment, and the method includes:

[0070] After the system is started, through the control of the processor, the speech recognition module and 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 HMM-based speech recognition engine;

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

[0072] Sending the digital sound signal to the processor, and at the same time the processor calls the speech recognition module in the dynamic memory, and compares the pronunciation characteristics of the speech pronunciation feature libra...

Example Embodiment

[0092] Example three

[0093] In this embodiment, the intelligent voice system of the present invention and its interaction method are further described through the 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 voice signal collection, voice signal sampling, amplification and pre-filtering and 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 illust...

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...
