Hello,
Sorry, this isn’t currently a feature of OpenEars. Generally, for long dictation tasks you are probably going to see best results with a server-based service. Even with live recognition, the end recognition result would probably be the same since it would be resolving the overall utterance using the same engine, acoustic model and language model. Based on my experimentation the advantages for long dictation tasks would be in better UI feedback (but doing speech-based correction on a single error in a long dictation is not fun for the user at all) but not notably different recognition results. The advantages of this kind of recognition are much bigger for shorter command-and-control models because reaction time will be faster for whatever you are controlling in addition to the UI advantage.
