Abstract
A kind of speech recognition controlled circuit, including voice, locally control chip and the audio decoder chip, crystal oscillator and the memory that connect with its signal, the audio decoder chip are connect by power amplifier chips with audible warning, and the audio decoder chip is also connected with microphone.Using speech recognition controlled circuit of the present invention, voice order can be understood, and exports the interactive voice for executing instruction and realizing close friend to operating unit；Using voice, locally control chip realizes local identification and study, is not necessarily to network module, simplifies usage mode.
Description
Technical field
The invention belongs to electronic circuit fields, are related to a kind of Artificial Intelligence Circuits, and in particular to a kind of speech recognition controlled
Circuit.
Background technique
In the prior art, household electronic products generally have multiple groups mechanical switch or remote control panel control, exist using not people
The case where property, remote control panel often can not find, be hard to tell, exists, and is inconvenient to operate in control process, is easy to happen maloperation
The case where.
Voice control technology can partially solve the problems, such as this, but the identification of existing speech chip depends on remote server
It carries out, local voice control circuit must be connect by wired or wireless way with server or cloud, and Yao Shixian voice is known
Not, generally necessary Configuration network transmission module, for network signal vulnerable to interference, transmission range is limited.
Summary of the invention
To overcome technological deficiency of the existing technology, the invention discloses a kind of speech recognition controlled circuits.
Speech recognition controlled circuit of the present invention, the audio solution for locally controlling chip including voice and being connect with its signal
Code chip, crystal oscillator and memory, the audio decoder chip are connect by power amplifier chips with audible warning, the audio decoder core
Piece is also connected with microphone.
Preferably, locally control chip is CI1006 to the voice, and the audio decoder chip is ES8388.
Preferably, the power amplifier chips are SGM4890.
It preferably, further include power management chip SY8088.
Preferably, the memory is the FLASH memory of W25Q64JVSSIG model.
Using speech recognition controlled circuit of the present invention, voice order can be understood, and exports and executes instruction to behaviour
Make unit, realizes friendly interactive voice；Using voice, locally control chip realizes local identification and study, is not necessarily to network mould
Block simplifies usage mode.
Detailed description of the invention
Fig. 1 is a kind of specific embodiment schematic diagram of speech recognition controlled circuit of the present invention.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in further detail.
Speech recognition controlled circuit of the present invention, the audio solution for locally controlling chip including voice and being connect with its signal
Code chip, crystal oscillator and memory, the audio decoder chip are connect by power amplifier chips with audible warning, the audio decoder core
Piece is also connected with microphone.
In specific embodiment as shown in Figure 1, audio decoder chip uses ES8388, and locally control chip uses voice
CI1006;Memory uses flash storage W25Q64JVSSIG.
It is that analog signal is input to audio decoder chip ES8388, sound by microphone acquisition after user issues phonetic order
Frequency decoding chip ES8388 gives voice local identification chip and carries out identification comparison after analog signal figure is quantified, voice is local
It is calculated after the local identification of identification chip CI1006 progress by artificial smartbook and judges to need what is exported to execute instruction, instructed
Synchronism output gives audio decoder chip ES8388, and audio decoder chip ES8388 is exported again gives power amplifier chips SGM4890, power amplifier
Chip SGM4890 controls loudspeaker playing audio signal, carries out prompting feedback to user.CI1006 external flash storage is deposited
Software program is stored up, crystal oscillator provides clock source for voice local identification chip CI1006, and power amplifier can use various chips, as long as energy
Identify that the outputs level signals of decoding chip ES8388, such as common SGM4890, crystal oscillator can choose YXS or crystalline substance
Precious brand.
ES8388 is a low-power consumption high-quality stereo audio decoding chip for aiming at portable audio player design,
It is integrated with complete interface, provides two stereophone circuit output ports, and built-in digital amplifier, directly props up
EQ balanced device is held to adjust and the enhancing of 3D audio and microphone/circuit output auto level control.
CI1006 is the voice local identification chip that Ying Tailun company volume production is opened in Chengdu, can carry out local identification, be not necessarily to
Audio signal transmission to other servers or cloud are carried out, so as to realize that local voice is known in the bad environment of network
, CI1006 is not also equipped with data-handling capacity, can export multiple analog or digital signals control other voice control devices or
Device, such as loudspeaker, switching tube.
The power supply of each chip can use power management chip output DC power supply to power for each chip, generally
DC/DC power supply chip, the DC/DC power supply chip are the power supply of voice local identification chip, specific implementation as shown in Figure 1
In mode, the DC/DC power supply chip uses SY8088.
Using speech recognition controlled circuit of the present invention, voice order can be understood, and exports and executes instruction to behaviour
Make unit, realizes friendly interactive voice；Using voice, locally control chip realizes local identification and study, is not necessarily to network mould
Block simplifies usage mode.
Previously described is each preferred embodiment of the invention, if the preferred embodiment in each preferred embodiment
It is not obvious contradictory or premised on a certain preferred embodiment, each preferred embodiment can any stack combinations
Use, the design parameter in the embodiment and embodiment only for the purpose of clearly stating the inventor's invention verification process, and
It is non-to limit scope of patent protection of the invention, scope of patent protection of the invention is still subject to the claims, all
It is that similarly should be included in protection model of the invention with the variation of equivalent structure made by specification and accompanying drawing content of the invention
In enclosing.
