Read Aloud transcribes the student audio and matched it to the passage for you. But it still makes mistakes. Close mis-transcriptions occur when a similar sounding word is transcribed in place of the spoken word.  eg 
"elegant" transcribed as "arrogant," or "their" transcribed as "they're." When using Poodll STT (see: Speech Transcription in Poodll ReadAloud ) to transcribe audio, the chance of mis-transcriptions is low. But browser speech recognition and strict speech recognition modes will often regularly mistranscribe the same words.

If this is a problem then you may want to "tune" your passage to minimize mis-transcriptions.  In some cases you might choose to edit your passage to be easier to transcribe.  In other cases you can do this by specifying "alternatives" which are acceptable mis-transcriptions. Here we will be dealing with tuning your activity by creating a list of "alternatives."

There are two ways to see how AI is transcribing your readings, via an attempt's grading page and via the Alternatives Admin tab. In both cases you will want to have a few readings of the passage completed, so that you have transcriptions to work with.

Using the Attempt Grading Page

1. Go into "grading" tab after ReadAloud has processed an attempt.
2. Tap the attempt's "Grade Now" button
3. Tap the "Transcript" button to set transcript mode
4. Tap on the "error" words to see what ReadAloud thought you said
5. Make a list of the mis-transcriptions
6. Add/edit the alternatives text area in the activity settings page or on the "alternatives admin" tab of the activity. 

Using the Alternatives Admin tab

1. Go into "Alternatives Admin" tab after some readings have been processed
2. Review the Summary of Mis-transcriptions table for acceptable mis-transcriptions
   The count and mis-transcriptions fields indicate how frequently a mis-transcription occurs. The table can be sorted using the triangle icons in the column headers.
   A number of identical mis-transcriptions indicates an opportunity to add an alternative.
3. Enter acceptable mis-transcriptions in the "Alternatives" field
4. Tap "Save and Re-evaluate"

Specifying Alternatives

Each ReadAloud activity has an "Alternatives" area. This is where you can specify which mis-transcriptions you will accept for the specified passage word.

e.g

In the alternatives text area the word sets above would be listed each on their own line separated by the | character. The first word is the "key", ie the passage word. The subsequent ones are acceptable transcriptions.

they're|their||they
apple|apples

NB You do not need to worry about differences between word case or punctuation. In fact is best to skip punctuation when writing alternatives.

For each common or likely mis-transcription make an alternatives entry.

No Phrases

You can not use multi word phrases as passage words or as acceptable transcriptions. Just individual words.

The following examples are NOT correct.

they are|theyre

invisible|in visiting

Forward matches

You will need to specify forward matches in a special but common case. That is when a single transcript word needs to match a two word phrase in the passage. 

e.g AI will often mis-transcribe "you are" as "you're" or "your"

But we can not specify multi word phrases(eg "you are") as keys in an alternatives set.  In the example case we could set "you" to "your" but then the second word "are" will not be matched by anything. To deal with this we can add a forward match before the closing pipe of the acceptable transcription. 

So the solution to the above examples, is below. This will mark both "you" and "are" as correct if "you're" or "your" is transcribed

you|youre are|your are

Wildcards

You can use a wildcard as an acceptable transcription. Though you can not use forward matches with wildcards.

e.g arikawa|*

Wildcards are applied after all the other matching is done. Any unmatched wildcard words will then be flagged as matched. So this would work: a|along long|*

Because the wildcard would not be matched until any other matching directives were applied.

NB You can not use forward matches with wildcards. 

The Final Syntax

So the final syntax looks like this:

passage-word | OK-transcription forward-match(optional) | OK-transcription forward-match(optional) |  ...

Common Alternatives

The following list might be useful as a start place base for English Read Aloud passages.

For all you copy and paste'rs you can copy this:

i|im am|ive have
you|your|youre are
he|hes is
she|shes is
they|theyre are
there|theres is
theyre|there|their
their|their|theyre
then|than
of|off
we|were are|well will
