|Raspberry Pi Speech Synthesis software|
Software for the Raspberry Pi Speech Synthesis project.
There are two files to download. The small file contains just the Arduino code and shell script. The large file includes the same files, plus a Raspbian operating system image that's ready to use.
The larger file could take some time to download on a slow connection. If you download the smaller file, you will need to install your own Raspbian operating system, or use an SD card that comes with Raspbian pre-installed.
The extra overlay file (TDA1543A-dtbo-SC.zip) can be used if the board is built using the TDA1543A IC rather than TDA1543; see Mailbag, December 2019.
|TDA1543A DAC IC|
A 16-bit Stereo DAC IC (DIP-8) which can be used to build the Raspberry Pi audio board (for speech synthesis etc).
Note that this A-suffix version is slightly different from the part originally used in that project and so you need to make some slight changes to the Raspberry Pi configuration for it to work. You can download the files you need to do this from: http://www.siliconchip.com.au/Shop/6/5097
|TDA1543 DAC IC|
16-bit Stereo DAC IC (DIP-8) as used in the Bad Vibes Infrasound Snooper and Raspberry Pi audio board (for speech synthesis etc).
