OK but that's not what I meant.
1) How are you playing the sound? Through some kind of speaker? What kind of speaker? Where is the speaker relative to the microphone?
2) How are you getting the audio to play when you are not home. Presumably there is some kind of software and or hardware involved that tells the computer to play a particular audio file based on some kind of event or input.
3) Why are you doing it this way? Playing a voice command seems like the hard way to do it. Is it just to prove that it can be done?
1) The audio is played through the brokerage software, then through basic computer speakers. I have adjusted the speakers from 3-4 feet away up to physically touching the microphone (usually with 60-90% confidence). All produce the same results, sometimes VC will hear it, sometimes it won't. With my voice, it's always dead balls on with a 95% confidence.
2) The brokerage software will play the audio when certain conditions are met of securities during market hours when I'm at work.
3) This is the only way I know how to do it. This is retail level software, there are no fancy bells and whistles, there are scripts you can write, but they wont execute orders due to liability, you must do that manually. The only output is an audio tone. Previously, I was using VOX activated form C relays, which you are very limited due to stereo channels, and the relay would often change state on ANY noise. VC allows for greater expansion and less errors (false alarms). Audio output is all I have, there are no modbus or analog/digital outs. Only mega huge brokerage firms get those options.
