Time Compressed Instruction

What is time-compressed instruction?

Time compressed instruction is audio that has been increased in speed, yet has preserved its quality.

What are the advantages of time-compressed instruction?

My research has shown that you can compress audio/narration up to 25% and still retain high level learning and problem solving skills as long as images are used in conjunction with the narration. This could save 25% of training time if done right, which is a significant time-savings.

What are examples of time compressed instruction?

Normal speech – 0% compression

Compressed at 25%

Compressed at 50%

How do I compress speech?

Check out my video on using a free program called audacity to do it. All you need to do is change the tempo speed. At 33% tempo change, time is compressed 25%
