Digital Voice Recorder/Playback (UM5100)


Posted on Jun 12, 2012

This Circuit is based on the UM5100 which can record speech into a digital memory and then play it back. The device is designed to be used directly with static RAM's up to 256K bits, or with EPROM 's or ROM's for playback only. High quality voice reproduction is possible and note that it is not a `computer voice`, it is the original speaker's voice played back. The bit rate is adjustable from 10kbs to 28kbs with higher quality at faster bit rates.

Thus the maximum length of recording can be between about 9 and 26 seconds. At low frequencies the auxiliary outputs should be used to avoid distortion, whilst for high frequencies, an internal amplifier intensifies the voice loudness.
