Here we are using many products using with Remote controller . Since we need to replacing the existing one to voice based control through IR transmitter. So We need to provide the voice MIC input to IR transmitter and get the output to IR receiver through IR LED.
Is it possible?

Example: You just tell " Play " the system will play the Song.

Have you investigated what it takes to accomplish this?

1 - Digitized the audio signal from the microphone using an ADC and MCU.
2 - Use voice recognition software to convert the sound to a command.
3 - Convert the command into an IR remote control data stream.

Interesting project


Lots to do here ,
yes its possible
as mentioned, it can get very complicated

its the sort of thing that Amazon and google spend a fortune on.

Thanks for your reply. As per your reply i understood that,
- MIC analog signal converted to Digital using ADC
- Digitized the audio data send to micro controller and convert the sound to command output suing voice recognition software
Upto this is ok. I under stood.

How this command converted into IR remote control data stream. This is for software code in Micro controller or need to provide any hardware option for the same.

Please explain some briefly.

Thanks in advance.

Presumably you are attempting to emulate a specific remote control. All remote controls generate certain codes for each key function. Every remote control is different.

Find your remote and its codes here:

How are you expecting to decode / understand the sound ?
any thoughts on algorithms ? techniques

"voice recognition software"

Any thoughts on, an off the shelf one or are you spinning your own ?

:) . But we are not using any keys. Only voice input through mic to IR portion.
Presumably you already know what needs to be transmitted in order to perform the current operations. Right? Somehow your system is already capable of using the IR transmitter to cause a song to play. Once you have recognized that the audio from the microphone is the word "play", you just send the exact same thing you are currently sending to the IR transmitter.
