HI
I have got speakjet ic to interface with pic controller in order to speak. But for testing, when i connect it with pc for the schematic shown in speakjet datasheet im not getting any sound for the input given from phrasealator software which is for speakjet ic. send me any schematic for getting speech output when i give input from pc also send any sample code to interface it with pic , Im using ccs compiler.. here is my schematic..

also tell me how to connect between max232, speakjet ic and DB9 connector..

regards
 

Do you want to connect MAX232 between SpeakJet and PC? If yes, then connect the MAX232 output Tx to SpeakJext TTL i/p. and Connect MAX232 i/p Rx to PC through D connector. If you just want to connect SpeakJet to MCU then you don't need to connect Tx pin of MCU to SpeakJet TTL Serial i/p pin.
 

I have tried with different possibilities for connection between them,if possible tell me with pin number of all three . also tell me how to give input from pc using phrasealator software..
