Common questions
How reliable are phonological features for pinning down a speaker's origin?+
They can narrow a speaker to a regional or social group with reasonable confidence when several features align consistently, but they rarely identify a single individual and can be affected by code-switching or accent adaptation.
Why do features like t-glottaling matter more than isolated word choice?+
Pronunciation habits are usually more automatic and harder for a speaker to consciously suppress than vocabulary, which makes phonological patterns a more stable and less easily disguised marker in disputed-speaker analysis.
Can a single unusual phonological feature identify a speaker uniquely?+
Generally no; a linguist builds a profile from a cluster of co-occurring features rather than relying on one trait, since any single feature can be shared across a wide dialect region.
