I may try some new setting for text to speech, but I never had any great expectations. There is so much authentic Russian audio I can capture and upload. The best part is I can generate transcripts from all that audio – and Lingq does a virtually perfect job of transcribing it. In this way I have both authentic native input and a transcript to read.
I do also recommend you check out the [Rooster Master LingQ - The Ultimate LingQ Enhancement Tool](Rooster Master for Lingq web extensions) to get even more value from Lingq.
