    I am working on an environmental project and am trying to teach young children to pickup rubbish and throw it in the bin.

    I am looking for a circuit or an IC that I can research to build a circuit around that I can use to playback a message.

    Any advice would be greatly appreciated.

    The most obvious choice would seem to be something from this collection of devices:

    https://www.nuvoton.com/NuvotonMOSS...?tp_GUID=d2589477-840d-4046-9c3a-2e0e457048b3

    Depends on how many units you are thinking of building?......most of the ICs in that collection are SMD, so you would have to budget to include for some development PCBs I would think..

    If you're only looking to build one device, than you might look at the simple circuit I attached to the bottom of this post:

    That can be built on stripboard.... see my prototype image attached to this post:

    This was all to do with creating a playback module for a kick drum, but would serve well for speech as well, with a much slower clock speed..

    As I say, depends on how many units you are thinking of building?....

    If you can still find one! ... not listed any more.:(
    Replaced by the range I linked to in post #2... which are nearly all surface mount devices, sadly......
