It is commonly noted that standard French is losing the contrast between its two low vowels /a/ and /ɑ/, due to the fronting of the back vowel. The difference in length, which accompanied the qualitative difference of this pair, is affected as well. In mainland France, this tendency can be found to various degrees across the country, and is spreading throughout the speech community. This article further develops the picture of the current status of the low vowel contrast by investigating Belgian and Swiss French, where length is known to play overall a far more prominent role in the vowel inventories than it does in standard French. Are Belgian and Swiss French also affected by the merger of the two low vowels? To what extent can a difference in length and/or timbre still be found? And how do the patterns of contrast neutralisation/preservation relate to the developments in France?
