Subtitling and/or voice overs onto video clips.

With iMovie HD6, you can add subtitles to your movies. To do this, click on the "Editing" button, and then click on "Titles". You can choose from a variety of titles in the menu.

You can also add a voiceover

From iMovie Help- _Recording a Voiceover_

Recording a voiceover
If you have a microphone built in or attached to your computer, you can record a voice to add narration to your movie.

IMPORTANT: Before you begin, check System Preferences to make sure your microphone is selected as the sound input device and the volume level for the microphone is not set too low (choose Apple menu > System Preferences, click Sound, and then click Input). You can turn the recording volume of your microphone up or down by changing the input volume in the Sound pane of System Preferences.

To record a voiceover:
1. Click Media, and then click the Audio button at the top of the Media pane.

2. Click the Record button (shown above) and speak into your microphone.
Speak clearly. While you are speaking, the input meter should be yellow. If it turns red, you are speaking too loudly.

3. Click the button again to stop recording.
The audio clip of your voice appears in the first audio track of the timeline viewer. You can drag the audio clip to align it with the appropriate video clips. For more information on working with audio clips, see Related Topics below.

Tip: If you don't have a microphone, you can use your video camera as a microphone. Record your voiceover with your video camera and import the footage into iMovie HD. Then select the imported clip and choose Advanced > Extract Audio. When the audio appears in a track below the video, you can delete the video track.

Best wishes on this project!

Hi

Think this should be very possibly with iMovie HD 6.

Text: Using the text tool and SubTitle to add in the text. Text needs a cut in the video-
clip to orient/start from. So I usually does:
• Writes down the text in a wordprocessor or Text-tool
• Open my movie and set a cut [cmd-T] from where texts should start
• Select Subtitling/text and copy in a propper part of the text
• drop the text-tool icon in-between where You made the cut eg Clip 1 and Clip 2
• localize wher next text-part should start and make a new cut
• repeat till all text is inserted

Voice-over: Not familiar with Your device but it should be able to speak out
Your text and this can be recorded into iMovie with the VoiceOver tool.
When You imported Your audio - this audio clip can also be cut and adjusted so
that it plays in concordance with Your movie but may be You need some hearing
assistanse to fine tune this. There is a Wave-form display in iMovie so You might
get help by that to orient the audio to match the video.

If your lightwriter has a headphone jack you might be able to patch the audio into the mic jack on your mac. You will need to change some set up settings in your pref file to get it to work. My students hook their ipods up this way to add music to their video's.

You could use your built in iSight camera to record and QuickTime Pro to edit.
QuickTime .mov files can have "Text Tracks" and up to 99 tracks in a single file.
I use http://www.ambrosiasw.com/utilities/wiretap/ to record anything that plays on my computer so capturing your text to speech is easy. QuickTime Pro can also play, edit and convert these recordings.
Apple includes many services and you don't need special software to speak text.
Use your mouse to highlight this paragraph and look under the Safari menu for the Services / Speech to play back an audio version.
QuickTime Pro is a powerful authoring application as well as a conversion tool. Two of my Web pages that use text tracks as examples:

Katilea,

does your lightwriter offers some 'export' of its audio as files (aiff preferred, or mp3 or wav.. )...?
then, it's quite easy: produce your 'readings'/voice overs and import them into your iM project at approbiate position...

switch on the 'show waveform' of the audio tracks.. you have a visual feedback where talk starts and ends..


start with a small test-project ... I'm afraid, it gets more tricky, than it sounds (pun intended 😉 )

as Kirk told you..
there's a tool (Wiretap) which allows to record any sound your Mac makes.. and your Mac is able to talk.. just tpy your text in any app and let the Mac speak.. Wiretap will record this 'audio' and you're able to place that into iMovie..


but...
those computer generated voices are.. computer generated, not too nice to listen for a long time. probably, it is MUCH easier, to ask one of your non-deaf friends to speak a few sentences..
