Hs anyone successfully mated a though hole speech synthesis chip with a Micromite, or even mated audio wave files with one. I've built and programmed a Micromite speed limit monitor and would like to replace alert beeps with voice! I should add that I am using an early 'Standard' Micromite chip.

My solution a few years ago was to create samples for the phrases I wanted and then play them from a DFPlayer - those little MP3 players with a serial interface and SD Card. still got several working today. The quality of the speech is very clear, depending how loud you want it, you might need a further amp on the output and you are away. Agreed it is only playing samples so not as flexible as true TTS but the end result was very good. Example DF Player on ebay Good Voice sample creating sample of four multi-language message I created. These were used in my customer feedback pods to convey a suitable message in the loos and remote areas (where an alrm may be heard only distantly) evac voices.zip I must say that the above voices, while excellent do sound a bit "deadened" and is some cases I processed the audio further by adding a little bit of echo - you can hear this on the test announcement. For the foreign language samples; my language skills are schoolboy at best so I relied on google translate to give me Rachael's lines in the required tongue then fed them into the correct language/voice in NR. They are all female as research has shown people tend to listen more intently to announcements in female voices... make of that what you will  I don't know if they still do it but I heard the USAF used to sample a pilots children for the flight systems to give critical messages, apparently the pilot is more likely to deal correctly with a situation if his daughter announces "your left engine's on fire Daddy"hth Edited 2020-05-11 18:50 by CaptainBoing |

Hi, I’ve used the Text-to-speech board, V8600A voice synthesizer from RC Systems Inc. (https://www.rcsys.com/modules.htm) in several of my projects. The modules are not cheap, costing about $89 US each. However, they create excellent results with clear voice in English. They interface via a com port at 9600 baud, TTL signal levels. So a connection to COM 1 or 2 on a 28 pin Micromite is a good solution. The text-to-speech is excellent, there are several voices to choose from, however I generally use the default voice. The board has a built in serial buffer, and an on board audio amp. If the unit is being used in a multi room building, I run the audio output into a distribution amp. I have one system installed in a location for more than 10 years announcing when doors are opened or closed as a audio security system. Hope this helps, have fun. |

I don't know if it would be sufficient on its own, or would suit your needs if mated with a micromite, but the ESP- and ESP32-based Annex Rapid Development system supports the SAM text-to-speech system: https://sites.google.com/site/annexwifi/projects/sam-speaker-network PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |
