Hi Martin and Lex,

Thank you very much for all the help.

Here is final script which help me to
1) query the website
2) download the wav file
3) extract the definition using Hpricot.

# download wav file
# extract the definition

require "rubygems"
require "mechanize"

mech = WWW::Mechanize.new
mech.user_agent_alias = "Windows IE 6"
mech.get("http://www.ask.com/web?qsrc=2352&o=0&l=dir&dm=&q=dictionary")

form = nil

form = mech.page.forms.select {|form| form.has_field?("aj_text1")}.first

if(form == nil)
abort "could not find form"
end

# query the website of word "filly"
form.aj_text1 = "filly"
new_page = mech.submit(form)

# download the wav file
wav_link = mech.page.links.select {|link| link.href =~/\.wav$/i}.first
puts "downloading #{wav_link.href}"
File.open(File.basename(wav_link.href),'w'){|f|
f.puts(mech.get_file(wav_link.href))}

# extract the information
doc=Hpricot(new_page.body)
puts
doc.search('div/span/table/tr/td').inner_html.gsub!(/<\/?[^>]*>/,"")
