Speech Time Calculator
Paste your text to estimate how long it will take to speak aloud. Perfect for presentations, speeches, podcasts and videos.
How It Works
This speech time calculator analyzes your text entirely in your browser — no data is sent to any server. Simply type or paste your text, and the tool instantly estimates speaking time at three different speeds.
Three Speaking Speeds
The calculator uses three standard speaking rates: Slow (100 WPM) for lectures and complex explanations, Normal (130 WPM) for presentations and public speaking, and Fast (160 WPM) for casual conversation and podcasts. These values are based on research into average speaking rates.
Practical Scenarios
The "Words Needed For" section shows how many words are required for common speaking formats — from a 5-minute speech to a 1-hour lecture. It also shows how your current text compares to these targets, helping you plan your content length.
Accuracy
The estimates are based on word count and average speaking speeds. Actual delivery time may vary depending on pauses, audience interaction, slide transitions, and your natural speaking pace. Use these estimates as a guideline when preparing your content.

Frequently Asked Questions (FAQ)
Q: How is speech time calculated?
A: Speech time is calculated by dividing the total word count by the speaking speed in words per minute (WPM). Slow speech is about 100 WPM, normal conversation is 130 WPM, and fast speech is around 160 WPM.
Q: What is the average speaking speed?
A: The average speaking speed for presentations and public speaking is 120-150 words per minute. Conversational speech is typically 130-160 WPM. Audiobook narration averages 150-170 WPM.
Q: How many words do I need for a 5-minute speech?
A: For a 5-minute speech at a normal pace (130 WPM), you need approximately 650 words. At a slow pace (100 WPM) you need 500 words, and at a fast pace (160 WPM) about 800 words.
Q: How many words for a 10-minute presentation?
A: A 10-minute presentation at a normal speaking pace (130 WPM) requires about 1,300 words. Adjust up or down depending on your natural speaking speed and whether you include pauses for audience interaction.
Q: Is my text stored on the server?
A: No. All calculations happen directly in your browser using JavaScript. Your text is never sent to any server. Everything stays completely private on your device.
Q: Does it work with different languages?
A: Yes, the calculator works with any language that uses spaces between words, including English, Spanish, French, German, Russian, Ukrainian, and many others. Speaking speed may vary by language.
Q: What speaking speed should I use for a presentation?
A: For most presentations, aim for 120-140 words per minute. This gives your audience time to absorb information. For TED-style talks, speakers often average 130-150 WPM. Slow down for complex topics and speed up for storytelling.
Q: Is this tool free?
A: Yes, completely free with no registration required. Use it as many times as you need.
