How many words are in an hour of audio?

How fast do people talk?

For conversational American English, the figure most commonly cited is about 120 to 150 words per minute. Prepared speech is often faster: one comparison of radio news bulletins measured about 168 words per minute on the BBC.

Spanish runs in a similar range when you count words. A 2015 study by Sandra Schwab (University of Costa Rica) measured about 153 words per minute for speakers from Costa Rica and 168 for speakers from Spain, and cites earlier work that treats 126 to 179 words per minute as a normal rate in Spanish. Spanish speakers produce more syllables per second, but Spanish words tend to be longer, so word counts end up comparable.

Real recordings include pauses, silences and people thinking, so the actual words per minute of a meeting is usually lower than someone's pure speaking rate.

Minutes of audio to words and pages

Estimates at 120 to 160 words per minute, and about 500 words per single-spaced page (double-spaced pages hold about half that). A transcript with speaker names and timestamps on every line takes more pages than plain prose.

Why it matters

• Typing it yourself: transcribing by hand usually takes about 4 to 6 hours per hour of audio, more with several speakers.
• Paying per word or per page: some human services and translators quote that way, so the table helps you budget.
• Reading and editing: a 1-hour meeting becomes a document the length of a long report. A summary of the decisions and action items is often what people actually read.
• Word limits: if a class or interview transcript has to fit a word count, you'll know how much to cut.

How many Dolcenota minutes a recording uses

Dolcenota counts the length of the recording, not the number of words. A 45-minute interview uses 45 minutes whether it holds 4,000 words or 7,000. If you combine several files into one transcript, their lengths add up.

The free plan includes 60 minutes a month, enough for about an hour of audio, roughly 7,200 to 9,600 words. Plus ($7.99/month) has 400 minutes, Pro ($14.99/month) 1,000 and Power ($29.99/month) 2,500. Each file can be up to 4 hours and 2 GB, and if one file would use more than half of your month's minutes, Dolcenota asks you to confirm before uploading.
