Official documentation

Google, 2026

Read on October 17, 2026

What it is: Google's Google Voice help article on checking voicemail. It says you can listen to voicemails or read their transcripts, warns that transcripts may be incorrect or missing, and gives the steps to turn voicemail transcripts on or off at voice.google.com.
How much weight it carries: Official Google documentation for a current product. It covers voicemail left on a Google Voice number, not a landline's own answering machine. Google's support site blocks automated fetches, so the archived copy was read.
