6.7 Conclusions and thoughts on speech recognition

Conclusions

Initially looking at the experiment, the plan was to have a text-dependent system, or a speaker verificationsystem, or something that could actually determine what word was being spoken to the system by the user. It has become painfullyclear that that would be a very difficult task to accomplish, and would require much more time, effort, and background on the subjectthan we could possibly acquire in a short period of time. Our system was, for what it did, relatively successful – it foundvowels with regularity, and it identified speakers at a rate of almost 70% - a very good rate for a basic system.

As obvious, however, is how much more in depth speech recognition is than the scope of our project. Being able todetermine what is spoken or who a speaker is with near perfect accuracy is an extremely formidable task. Preventing anotherindividual from breaking into the system can be just as difficult, as it requires a system dependent on text and a system that willnot accept anything other than what it specifies. Our initial idea of being able to determine what word was being spoken is, at best,naïve, and at worst not at all feasible. With that said, however, the end results were very acceptable.
