I am looking for studies that investigate the neural mechanisms of inner speech. PubMed searches only seem to produce studies on hallucinations in schizophrenia. I wonder if there are studies on everyday inner speech, i.e. thought.
This seems to be related:

What a fascinating question. A bird model might be suitable for the study of the mechanisms underlying inner speech, or "inner song." The zebra finch in particular would be a good model. I recommend looking at the work of Ofer Tchernikovski. He looks at song development and translates his work to human speech development. Your question looks at the other side to speech development. Potentially you could employ a bird model with cognitive tools to measure neural correlates that underlie inner song. Best of luck with your research.
A couple of recent articles from 'New Scienitist' magazine:

It might not be the exact topic you're looking for, but there are a few researches on subvocalization which might be of interest or at least provide some inspiration: http://www.ncbi.nlm.nih.gov/pubmed/?term=subvocalization
There has been quite a bit of work on Trains of Thought especially with regards to mind wandering, but I am not sure that they have tried to capture the internal speech.
