Enter the total number of words and words per minute rate into the calculator to determine the total time for speech. This calculator can also evaluate any of the variables given the others are known.

Text To Speech Time Formula

The following formula is used to calculate the time it takes for text to speech conversion. 

T = (N / WPM) * 60

Variables:

  • T is the total time for speech (seconds) N is the total number of words in the text WPM is the words per minute rate (words/minute)

To calculate the time for text to speech conversion, divide the total number of words in the text by the words per minute rate. Then, multiply the result by 60 to convert the time to seconds.

What is a Text To Speech Time?

Text To Speech Time refers to the duration it takes for a Text-to-Speech (TTS) system to convert written text into spoken words. This can vary depending on the length of the text, the complexity of the words, and the speed at which the TTS system is set to read. TTS technology is used in various applications, including assistive technologies for visually impaired individuals, voice assistants, and more.

How to Calculate Text To Speech Time?

The following steps outline how to calculate the Total Time for a Text To Speech.

  1. First, determine the total number of words in the text (N).
  2. Next, determine the words per minute rate (WPM).
  3. Next, use the formula T = (N / WPM) * 60 to calculate the total time for the speech.
  4. Finally, calculate the Total Time for the Text To Speech.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total number of words in the text (N) = 500

words per minute rate (WPM) = 150
