Here are some tools I use for data analysis...

 

Processing and plotting acoustic meaurements of vowels using R

Part 1 - processing the data

Part 2 - plotting the data

 

 


Use R to compile all of your small data files into one big data frame

 


Add polynomial terms to your data frame for growth curve analysis

 


Convert sound frequencies to various scales
(convert frequency difference to octave diff or cochlear space difference, etc)
(an excel file)

 


Observe context effects in identification functions

 


See how sample size affects means comparison

 


See how random effects structure can help to estimate fixed effects
