I had this one project where the device was supposed to speak out the output. And I was too Lazy to actually go and build a PC based application and not that lazy to make it on a micro controller. So here is some of my research where i am gonna show you how to do speech synthesis for your Embedded Project.
Why I am Implementing it on a Microcontroller?
-Its Cheap
-Its Portable
-Its Fun
-Its Easy ( Yes! Once you Port it on your platform, it is)
What do we need here.
-A low power Speaker (8 Ohm one will match the impedence)
-A Micro controller with PWM generation possible and lots of memory ( We are using Atmega128)
-A low pass filter adjusted on 8Khz Band.
“Why wav? well they are said to be the one with higher compression ratios eating out lowest memories. ” – Thanks, I did need a good laugh (even if it’s more like a sneer). Especially considering there’s no compression involved in the project at any point. Tell you what – unless all you need to say is “on” and “off”, either get a hardware sound storage / playback chip, or use a micro with SD card access…
A bit disappointing, this, it’s just playback of recorded speech, not speech synthesis.
In what way I can make that ? Please tell me more
