Lots of evidence that genetics have a large influence on early language development, especially speech, if you care to look. E.g. this study finds genetics contributing over 60% of variance: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3851292/

No doubt when we start looking at impairments and deficits that you can find plenty of situations where a high proportion of the phenotypic variance is heritable. But when you restrict the study to the top 60th to 95th percentile (which we are discussing here) I don't think you will find particularly strong relationships.
