AUdacity for Listening and Speaking material development

  1. 1. 1/29/2009 A Workshop on Enhancing Listening and Speaking Skills Using Advanced Sound Editing Software - Audacity Dr. Dilip Barad, Dept. of English Bhavnagar University Bhavnagar. 1
  2. 2. 1/29/2009 Major concern as e-resource developer… WHY? HOW? • Today, English teachers of S/F language are constrained to become familiar with emerging learning technologies. • Not only that, s/he has to use resources prepared by other teachers, but also to prepare his own e-resources and e-materials. 2
  3. 3. 1/29/2009 Key Issue…. • Well, the major problem is that it is not all English teachers’ cup of tea. • In such case what can be done??? 3
  4. 4. 1/29/2009 Using existing software / programme / web resources… • The best of all idea is to use existing e-resources available. These software are primarily prepared for other purposes but can be utilized for ELL. • So, if a teacher wants to improve writing skills of the students, he can use MS Office - Word, writeboard,, orkut, face book, moodle -LMS, wikieducator etc. • If reading skills need to be improved, again above mentioned e-resources can be effectively utilized. 4
  5. 5. 1/29/2009 From LSRW, LS skills and available resources… • So far as RW skills are concerned, available resources can be of immense help to teachers. • But the million dollar question is ‘how to make effective use of available e-resources for LS skills’?? • B’coz listening and speaking skills are different than the other two skills it needs to be given special attention. 5
  6. 6. 1/29/2009 Available LS skill development material and its disadvantage… • Most of Listening materials used in the class of ESL/EFL are developed by native speakers. • These western courseware are designed to meet general purposes and therefore cannot address needs of learner in specific context. • Often they are culturally biased (Supiyan, 1996). 6
  7. 7. 1/29/2009 Preparing LS skill material and its advantages… • If listening skill material is developed by the teacher looking at the level of students and context, it contributes to skill development. • Studies have reported that learners respond to computer aided / mediated teaching learning materials produced by their own teachers more effectively than prepared by other agencies (Bloomer, 1985). 7
  8. 8. 1/29/2009 Major difference in language lab and sound editing software: Features Language Lab programme Audacity, Praat, Wavepad, Audition, sound forge etc 1. Voice Recording Yes Yes 2. Measure frequency – Yes Yes* voice modulation of recorded voice with pre- recorded voice 3. Models of pronunciation Yes* No – pre-recorded 4. Editing Recorded Voice No Yes 5. Preparing listening skills No Yes test 8
  9. 9. 1/29/2009 But how to do it?? Is it easy to do it?? Can all teachers do it ?? • Here again, the teacher need not sit with the programmer to prepare programme/software. • S/He just has to use some existing software or download some open-source sound editing programme and learn the basics to operate it. • It is as easy as child’s play: - Record, Edit and Play… • And see how wonderfully you can teach your students the most useful skills – listening and speaking. 9
  10. 10. 1/29/2009 Audacity - Sound editing programmes • There are several such software available at premium cost as well as free-ware . • Eg. Audacity, wavepad, praat, Adobe Audition, Sound Forge, Magix audio cleaning lab, Goldwave, etc… • We shall have hands on experience of how to record and edit sound on Audacity. 10
  11. 11. 1/29/2009 Outline of the workshop • Overview of Audacity interface: record, cut, copy, paste, delete, insert, silence, pluck … • Demo of audio effects: amplify, normalize, equalize … • Participants record a self-introduction of 1 min duration and improve their recordings using features of Audacity. • How to download and install? (Audacity, LAME and FFmpeg) • How to convert audio files into mp3 format? 11
  12. 12. 1/29/2009 Why Audacity? •Audacity is one of the most frequently downloaded digital audio editors in the world. * Tens of millions of people have used it to record a podcast, create a demo CD of their garage band, transfer old vinyl records to CD, or just have fun with audio. •But there are dozens of other software programs with similar capabilities...why should you choose Audacity? •The simplest reason? Because it's free. •Another reason to choose Audacity is that it's the only audio editing software that runs on Windows, Mac and Linux computers. •The most important reason - easiest to use •Audacity is not likely to die: Open-Source Software 12
