I have a few questions.

1. For numeric 10 and onwards, I use numerals instead of words right? For e.g. 11, I use 11? And 8, I use eight? Correct.

2. For percentage, like 4%, I use 4% instead of four percent right? For 90%, I use 90% instead of ninety percent? Correct.

3. For 1st, 2nd, 3rd and 4th, I use first, second, third and fourth right? How about for 65th anniversary, do I use 65th or sixty-fifth? Do I follow the numeric rule? Yes, please follow the numeric rule with 10 as the cutoff.
this means that you need to spell out first through ninth but use numerals over ninth (10th, 11th, 12th … 99th, 100th.

4. Is non-verbal like laughter important? Because in a tape, laughter appears very often so do I use [laughter] for all the laughter I hear?
Sometimes it is necessary so that the reader knows the state of mind of the speaker when the audio was spoken.

5. Are “you know”, “sort of”, “well”, “all right” and “ok” filler words?
Not necessarily. Mostly we refer to filler words as those like:
uhms. uh. etc. (Unless the uh uh is needed to signify that the speaker agrees to a particular point. (in which case we usually let it slide)

6. There is a table of preferred spellings in the guide. Do I always following that table? For e.g. color, I normally use British spelling “colour” instead of American spelling “color”. I also use “alright” in the past, so do I change to
using “all right”? For local tapes, do I use British or American spelling?
Mostly it will depend on our client. We do have British clients, so we need to use british english for those.

7. The guide mentioned – if you can change the “its” in your sentence to “his”. Does it mean that strictly no “its” in transcripts? For e.g. “The dog is going back to its home.” Do I use “The dog is going back to his home.”?
Nope. The guideline merely give you a ‘test’ if the sentence makes sense with the use of ‘his’, then ‘its’ is appropriate. It does not mean that you should substitute HIS to ITS.

The most common error is between ‘its’ and ‘it’s’ (the contraction of it is)

8. For title like “Dr”, do I use “Dr” or “Dr.” (with or without a full-stop after Dr)? For title “Miss”, do I use “Miss” or “Ms”? For title “Madam”, do I use “Madam” or “Mdm”? In case of doubt i would spell out the word. ( I will have to consult the Chicago Manual of style on this one thought)

9. For title of a book or movie, are the following style/format correct? (with quotes round the title and capital letter for every word) I love the movie “I Am Legend”. I love to watch the latest TCS show “The Golden Path”. My favorite book is “The Road Less Traveled”.
