Speechmarks missing `playerOffsetInMilliseconds` #3

Open jayeheffernan opened 4 years ago

jayeheffernan commented 4 years ago

I'm trying to modify these examples to be able to sync an animation on a Raspberry Pi to the voice of an Alexa Echo. I am receiving the speech data, but is seems to be missing some of the data required to sync. The documentation for the speechdata interface (linked to in your README, here) suggests:

To determine how to sync speechmark data to Alexa's speech, use startOffsetInMilliSeconds minus playerOffsetInMilliseconds.

The packets I am receiving look just like the example in the README:

# Speechmark
{ {'payload': {'speechmarksData': [{'value': 't', 'type': 'VISEME', 'startOffsetInMilliSeconds': 708}]}, 'header': {'namespace': 'Alexa.Gadget.SpeechData', 'name': 'Speechmarks'}} }

They have a startOffsetInMilliSeconds, but no playerOffsetInMilliseconds. Any idea how to sync an animation to the speech data without this value?
