The predictions about stress cannot readily be tested for Livonian since the etymological long vowels triggering gemination later reduced quantitatively and qualitatively to schwa.
Is primary gemination associated with greater phonetic duration than other lengthening phenomena, i.
excluding the gemination effects triggered by a following long vowel, whereas the Ingrian examples are transcribed with lengthened consonants before long vowels.
These consonants most affected by lengthening are those targeted by the historically earlier process of primary gemination that is also found in many Finnish dialects.
The longest of the lengthened consonants, the one in CVCVV feet arising through primary gemination, differed from all other phonemic short consonants, but did not differ from any of the phonemic geminates.
