Sorry for late reply . Sir as I have explain what is our project all about we are just working on text to speech further we r going to used it in robot.It must be done using aurdino UNO. And if there is any modifications in circuitry plz inform it as soon as possible sir. I am in great need plz sir can u help with it as soon as possible. We are also doing with speaker driver circuit using LM386. Sir its quiet urgently required
so please help to get the pure sound and other upgradation plz rply sir

thats exactly what is happening with me also.... I also have an arduino uno. Thanks for any help and thanks for the great project.

The quality is what it is I'm afraid.

Which pin are you using for output?

[tjodork1960]

digital IO pin 3 which is the 4th from the end

[jscrane]

Please try digital I/O pins 9 or 10 instead, I think pin 3 has a much lower PWM timer resolution: this is a hardware issue.

Please also read this document which describes how PWM is used in this library.

I tried pin 10 but it doesn't really sound much better.
I need to confirm .... can I output this right to an amplified speaker ? there was some mention of a resistor and capacitor...are they necessary ?

hello,Issue is not solve here i have also study and try the talkie library and run the code .but the problem in this code that is its play only those word who are predefined in the header or source file.problem is that how to defined the own word in this . so i suggest you sir plz read this library code if you having any other solution on please tell me also .For defined own new word we have to used audacity or other thing which are new for me .If you have a better solution and easy technique to add new word please tell me .REPLY AsSoonAsPossible . I'm waiting for ...
Talkie-1.0.2.zip

i am also having the same issue. I tried all the pins you said. It dosnt work. In the example, it said to connect an amplifier. Will it work if i connect it ?
