Discussion Overview

The discussion revolves around the feasibility of implementing Bluetooth voice command recognition for a microcontroller application, specifically targeting the Motorola HC08 or HC11 families. Participants explore the requirements for voice recognition technology, including speed and trainability, and seek recommendations for suitable hardware components.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • deCraig expresses a need for a Bluetooth solution that can send a limited number of voice commands to a microcontroller, emphasizing the requirement for a fast and trainable voice recognition chip.
  • Warren questions the practicality of using an 8-bit microcontroller for voice recognition, suggesting that more computing power, akin to a Pentium 4, would be necessary.
  • Another participant mentions the existence of ASICs that may facilitate limited speech recognition, referencing cell phone applications as a potential source of technology that could meet deCraig's needs.
  • deCraig shares an example of a personal experience with voice recognition on a cell phone, indicating a willingness to consider this approach if other options are unviable.

Areas of Agreement / Disagreement

Participants have differing views on the suitability of using an 8-bit microcontroller for voice recognition tasks, with some suggesting that more advanced computing resources are necessary. The discussion remains unresolved regarding the best approach and technology to use.

Contextual Notes

There is uncertainty regarding the specific requirements for the voice recognition technology, including the necessary processing power and the availability of suitable hardware components. Participants have not reached a consensus on the optimal solution.

I'd like to send, via bluetooth, a small number of commands--perhaps as many as 20 words. I'd like to send the decoded commands along to one of the motorola HC08 or HC11 family of microcontrollers.

The voice chip needs to be trainable and faily fast. Perhaps 50 msec delay.

Does anyone know who manufactures bluetooth recievers or speaker independent voice decoders? This arena is new to me.

You're going to need computing power probably equivalent to a Pentium 4 to do voice recognition. Why would you couple that to an ancient 8-bit microcontroller?

There may be some ASICS or something that help with this kind of limited speech recognition -- I've seen some cell phones with voice recognition for dialing numbers from the phone number list in the phone, for example. The wikipedia.org entry on Speech Recognition is pretty well filled out. Maybe start there, and look into the cell phone application angle to see if there are ASICs available already to give you the limited recognition you are looking for...

Thanks berkeman.

My wife has her cell phone rigged up for word comparison. You program it by associating a spoken name with a phone number in your address book. To get it to dial the number, you say "call" and then the name--and it all fits in a cell phone, of course.

Thanks for helping me look into it better. I could take this approch as a last resort.

BTW, I did already try Wiki. They weren't all that helpful with the nitty-gritty.
