Guinness World Records does not currently monitor a record for the longest time without speaking. While there have been instances of individuals attempting prolonged periods of silence, such as during meditation retreats or personal challenges, these are typically self-imposed and not officially recognized as world records.
It’s important to note that Guinness World Records has discontinued certain categories due to health concerns or other reasons. For example, records related to hunger strikes and fasting were discontinued because of health risks.
If you’re interested in records related to silence or speech, Guinness World Records has categories like the longest time without speaking, but these records are not currently monitored.
