Hi, I searched a lot for this chip to buy one for me. There may be other better chips available cheaply now - perhaps someone else may suggest some. For the 3-sine version, the compression ratio assuming 8kHz, 8-bit, wav file is better than If you include this in a test program , you have available all the spoken digits. It would be cheaper in hardware cost to have the MCU directly make speech.

This would make a compact flexible system. The audio quality should sound good enough for most purposes. Do a search for "SP" and you'll find it. Is there anyother part or manufacturer doing the same thing?
Allophone PIC Talker Thingy
Forums New posts Search forums. The software supports both externally controlled speech wherein a host PC or processor sends the allophone codes one at a time for the PCTalker to say, and speech initiated and controlled from within the PIC SW.
Let me know if you have any other questions. Commas were placed between the digit names for synthesis.
You could do worse than something like this? The reasons for a new version of the SSD library are: Although these speech modules come in handy, their price range seems a bit high for many projects.
Voy a poder probarlo.
English text to speech on a PIC microcontroller
Hope you will get this working. With the PAM, you can just feed the input audio to the amplifier and connect the speaker to the module directly without any external components. Hi all, Can anyone suggest me a cheap speech synthesizer for my PIC project? This is due to the lack of a rule database to convert text to phonemes, presumably due to the limited amount of memory available.
Unzip these into a suitable directory: It is anticipated that this will be sufficient information for a PIC-proficient experimenter to build and use a similar speech synthesis system. Notify me of new posts by email.
The only challenge was to get all the bit data types in the original source pictalkfr ported properly to the bit architecture of the PIC24 micro-controller, and to get the rule and phoneme database fit nicely into the PIC24FJ64GA available memory. The problem with this approach is that it takes a lot of memory and is not very flexible.
Using pictalke method, we can trade off quality and compression. FM transmitter circuit not working Started by polashd 38 minutes ago Replies: You will probably need a professional sound editor software such as Goldwave to play and examine the generated file.
Connect the DB9 socket to a serial port on your computer. I'm thinking something along the functionality of the old General Instruments SPO where each phenom would have a unique address value and you just send it a string of addresses to spill out synthesized speech There are approximately 44 phonemes in English to represent both vowels and consonants.
The main problem with this code is that it requires a 64kbyte table, which would fill all of flash on the Mega32, but could be put into serial dataflash separate chip. It is therefore better to compile with the default settings and use the PIC24FJ64GA or one with more memory to save the trouble and have more code space for other purposes.

Although the voice still sounds robotic and there are some mispronounced words, the overall quality should pictalkrr good enough to be used in embedded projects, as a free alternative to pictxlker commercial text to speech solutions. It would be cheaper in hardware cost to have the MCU directly make speech.
You can use the circuit in step 2 RC filter of this article http: Click here to register now. There is an interesting project to re-create that chip using a pic micro at: These pages describe Ipctalker and include the circuit diagram, the PIC source code, the allophone file and an allophone file downloader program.
