Can i send voice notes in realtime through a mic to a php using esp8266 where audio will get processed.
I don't know it's possible or not so i'm asking you any suggestion or reply will be appreciated.
Thanks & regards

Yes that's possible. Voice can be quite low fidelity recording and still be more than OK.
I would start looking at the ESP Baby monitor project for ideas:

The ESP8266 does have a (single) I2S interface, so you can connect an ADC. It may even be fast enough to capture at 44.1 or 48 kHz. I am not sure if the processor itself (at 80 or 160 MHz) is quick enough to do any processing or packaging to WLAN at that speed.
Only drawback is that the I2S interface is really poorly documented.
You might consider using an ADC with a SPI interface instead or even I2C (lower sample frequency due to lower bus speed, though).
