[hi-ogawa]

what SpeechApi service does

• state (on/off)
• always return what word is recognized (by word, by sentence?)

[hi-ogawa]

what watch controller does

• hightlight word based on the info from SpeechApi service

[hi-ogawa]

• language should be chosen between american or british (or more)

[hi-ogawa]

try two types of highlighting

• one is just highlight words included in 2nd result transcript
• the other one is compare some continuous words against the end of 1st result transcript
