Digital Equipment Suggestions

Going digital for language samples is a relatively easy process. Digital files improve the overall quality of the language sample and simplify the transcription process. There are three basic steps to working with digital files: 1) record the language sample with a digital audio or video recorder, 2) transfer the digital file to your computer, and 3) control the playback of the digital file while you transcribe the sample.

Digital Recorders

There are a multitude of digital recorders on the market, including IPads and other computer tablets, as well as most smart phones. For an inexpensive recorder, the Olympus VN-722PC offers a quality recording, ample recording time, and is priced around $60.

Using an iPad, iPod, or iPhone to record samples

Recording Samples

  1. Download the free version of iTalk Recorder to your Apple device.
  2. Open iTalk.
  3. Choose a recording quality; it's OK to go with "Good" if you are in a quiet environment.
  4. Press the big record button.
  5. Press the record button again to pause or stop.
  6. Add a "Recording Name" (speaker id, context, and date; e.g., P123 Expo 5/12/2014).
  7. Press "Done" to switch to the review screen.
  8. Mistake recordings can be erased by pressing "Edit" in top left. The delete feature works as it does in all Apple apps.
  9. To make another recording, press "Record" in the top right.

Transferring Samples to a Computer:

  1. Plug your device into a computer with the cord used for charging and syncing.
  2. Open iTunes.
  3. If your device is set so it should NOT automatically sync when plugged in:
    • Look on the left panel for "Devices".
    • Click on the name of your device.
    • Click on the "Apps" button towards the top center.
    • In the "Apps" box on the left, click iTalk.
  4. All audio files from the iTalk app will appear on the right in the "iTalk Documents" box. Click on the audio file you want and then click "Save to" to save it wherever you prefer. Generally it makes sense to use one folder to hold all your audio files and then you can subdivide into more folders, e.g., one for each speaker. If you ask SALT Transcription Services to send you the Standard Measures Report or any other analysis, they can send you a PDF that you can save directly into that speaker's folder along with the transcript. This is especially helpful when you use SALT to compare different speaking contexts (e.g., narration vs. conversation) or to monitor progress (Time 1 vs. Time 2 for retelling the same story).

Digital Play-back Options

There are several options for controlling the playback of digital audio files for transcription. If you're doing a lot of transcription, invest in a good foot pedal control as it will reduce the transcription time and improve the overall accuracy of the transcript. If you're just getting started or your budget is limited, check out the software options.
