Speech Synthesizer IC

This project is produce an single chip speech synthesizer exactly or somewhat like the old GI SP0256-AL2 IC or the new Magnevation SpeakJet IC using an small microcontroller like a Microchip PIC, Atmel AVR or Cypress PSoC. Preference is the PSoC device but I am open to other MCU's. Sound is generated either by DAC or PWM. The SP0256-AL2 used LPC compression to generate phonemes which allowed some smoothing between sounds. Phonemes are synthesized in real time using either LPC or some other low bit rate audio compression. I am not interested in approaches where SP0256-AL2 samples are played back from EEPROM. MCU will accept data over a serial port. Data is single byte data where each byte represents a single phoneme or timed silence. The phoneme set can be the same as the SP0256-AL2. See the SP0256-AL2 datasheet for more details. I would consider other phoneme sets if you have better suggestions. I already have a english text to speech algorithm I can use to convert English text to SP0256-AL2 or other phoneme codes but would be interested in other TTS alogorithms if you have suggestions. I can provide recordings of phonemes as needed. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
