Microphone quality makes a great difference in the quality of speech recognition results. And although the microphones integrated in iOS devices are generally good and give decent results, positioning the device in a way that is ergonomically viable for efficient dictated translation - and concurrent keyboard use - is not always so easy. This is a potential barrier to the effective use of Hey memoQ speech recognition.
So a good external microphone may be needed. But with recent iPhone models lacking a separate microphone jack and using the lightning port for both charging and microphone input, connecting that external microphone might not be as simple as one assumes. Especially not someone like me, who is rather ignorant of the different kinds of 3.5 mm audio connections. I have had a few failures so far trying to link my good headset to the iPhone 7.
Colleague Jim Wardell is not only the most experienced speech recognition expert for translation whom I am privileged to know; he is also a musician with extensive experience in microphones of all kinds and their connections. And recently he was kind enough to share the video below with me to clear up some misunderstandings about how to connect some good analog equipment to use with Hey memoQ on an iPhone 7 or later:
