Would anybody happen to have audio records of the Romaniote (Greek, say from Janina) Torah readings?
I don't want to accept my own answer, but I found this video of Shema being recited in the Romaniote tradition with the te'amim. Also, the website of Kehila Kedosha Janina has some samples of their liturgy. They seem to be chanting the last portion of Shirat ha-yam according to the te'amim. The link @Oliver shared also seems to contain a sample of Shema.
I'd still appreciate if somebody can provide me with another resource, and will probably accept their answer instead of mine.
