# Speech Time Calculator

> The average speaking rate for conversational English is about 130–150 words per minute (wpm); slides run slower (100–125 wpm) and audiobooks faster (150–160 wpm). This free speech time calculator divides your word count by your pace, so a 1-minute speech is about 120–150 words and a 5-minute speech 600–750.

- Demo "Trustworth Man" (English, MiniMax Speech 2.8 HD, Speed 0.85×): script: Thank you all for being here tonight. When we started this project three years ago, we had one borrowed laptop, a kitchen table and a very stubborn idea. Tonight, that idea is used in forty countries. None of that happened by accident. It happened because of the people in this room.

## Steps
1. Paste your speech (or type a word count) — The calculator counts words in your browser; nothing is uploaded.
2. Choose a pace — Slow (100), Slides (120), Audiobook (150), Fast (170) — or drag the slider from 80 to 220 wpm.
3. Read the result — Speaking time, word count and a “with pauses” estimate that adds a beat for each sentence.
4. Work backwards if you need to — Enter your time limit to get the word budget, then press “Hear it read aloud” to hear it in an AI voice.

## In depth

### The formula
Speaking time in minutes = number of words ÷ words per minute. The hard part is choosing the rate. Audiobooks are recommended at 150–160 words per minute, which is the range people comfortably hear and speak, while slide presentations tend to be slower, around 100–125 wpm [1]. Auctioneers can reach about 250 wpm [1].

### What slows a speech down
Your real time will be longer than the raw estimate when a speech has:
- Pauses for effect — every deliberate pause adds a second or two.
- Audience reactions — laughter and applause.
- Slides and demos — you stop talking while people look.
- Numbers, names and technical terms — slower to say than to read.
- Nerves — which usually do the opposite, so practise slowing down.

### Using an AI voice to rehearse
Paste your speech into the Voice Studio and listen to it read aloud. You'll hear clumsy sentences and missing pauses immediately. AI voices read quickly at default speed, so set speed to about 0.8× to approximate a stage pace, and use the clip length as a sanity check on the calculator.

## FAQ
Q: How many words is a 5-minute speech?
A: About 600–750 words at a typical 120–150 words per minute. For a slower, formal delivery, aim for 500–600.

Q: How many words is a 1-minute speech?
A: About 120–150 words. A lively delivery can reach 160–170; a slow, ceremonial one about 100.

Q: How many words per minute is a normal speaking rate?
A: Conversational English averages about 130–150 words per minute, and most estimates put comfortable speech between about 120 and 160. Slide presentations tend to run 100–125 wpm, and audiobooks are recommended at 150–160 wpm.

Q: How long is a 1,000-word speech?
A: About 7–8 minutes at 130–150 wpm, or 10 minutes at a slow 100 wpm.

Q: How does the calculator count Chinese or Japanese text?
A: Latin-script words are counted by spaces. For Chinese, Japanese and Korean characters it uses a rough equivalent of 2.5 characters per spoken word, so treat the result as an estimate.

Q: Is my text uploaded?
A: No. The count runs in your browser. It's only sent to the Voice Studio if you press “Hear it read aloud”.

Q: Why does the AI voice read faster than my estimate?
A: AI voices at default speed read briskly — about 195 wpm in our test on this page. Lower the speed to about 0.75–0.8× to match a typical presentation pace.
