Summer Lab Report

I handed my chosen passage to the subject and instructed them not to begin reading until I told them to. I started the recording device (my mp3 player) and told my subject to start. I started the stopwatch timer when they began to read. When the subject was finished reading I stopped the timer and the recording. Then I hooked my mp3 player to my computer, took the recording of the subject, and played it back in slow motion using Audacity. I followed the subject's words and marked off any words that were mispronouced, skipped, or slurred on the paper they read from. I divided the number of wrong words by the number of words in the passage (124), and then multiplied that number by one hundred. The final number is the percentage of incorrect words. I created a table for each subject's time and accuracy. I had eleven subjects. After I had tested each subject I added all the subjects' accuracy percentages together and divided that number by eleven (the number of subjects) to get the average accuracy, and then added all the subjects' times and divided that number by eleven to get the average time.

To perform this experiment I needed:1. Test subjects2. Audacity or another program that can slow down the recorded speech3. 100-200 word passage for the subject to read4. Timer/stopwatch Scroll down5. A device that can record the subject's speech (I used a recording function on my MP3 player)6. Pen and paper for notes7. Printer and computer8. Calculator to find accuracy percentage

Materials

Procedure

My hypothesis proved to be incorrect! As shown above, speed seemed to have nothing to do with accuracy. Reading quickly does not imply inaccuracy. The average speed of the subjects is about 40 seconds. Their average accuracy is about 95%.

Result

Summer Lab Report

I believe that the slower you talk,, the more accurate you will be. I think that the average fastest a person can talk with accuracy will be about 60 words per minute, with 90% accuracy.
