The ME 3 is recommended by some people for use with speech recognition software.. Whilst it is a very good quality microphone and gives good results, it is not ideally suited for this use out of the box..
The Sennheiser ME 3 microphone is designed for use with our radiomicrophone bodypack transmitters and comes fitted with a mini-jack with a locking ring.
This locking ring will prevent the microphone from being connected directly to most PC's. Also the standard ME 3 is not wired correctly for being connected to a PC.
To use the ME 3 with a PC for voice recognition, the mini-jack connector must be cut off and rewired with a standard mini-jack connector with the correct wiring configuration for use with a PC. This would be wired as:
These come with the correct connectors for pluging straight into a computer (or in some cases smartphone or tablet). They also have the advantage of being a headset which incorporates a microphone and headphone, so can also be used for telephony purposes.
Some models also have a noise cancelling microphone, which helps in reducing background noise getting into the microphone, so would be better suited to use in noisy environments.
