A simplified version of our speech recognition click board.
With SpeakUp 2, we managed to fit the speech recognition firmware onto a single chip, a 32-bit FT900. This allowed us to produce a board with a simplified hardware design and a lower price.
There are some performance trade-offs, but those will be irrelevant for many people. For example, SpeakUp 2 can be programmed for 100 voice commands, while the original SpeakUp could do 200. Also, SpeakUp 2 can accept commands up to a second long, while the original could accept phrases up to 5 seconds long.
Think of SpeakUp 2 as of a MacBook Air compared to MacBook PRO (the original SpeakUp).
Here's the video to summarize the differences:
Both SpeakUps can be programmed with the same SpeakUp software utility.
