Requirement for UA / SS protocol

Hello,

 

On the Nov 18th conference, I volunteer to send out proposed wording for
a new requirement:

 

 

 

Summary - User agents and speech services are required to support at
least one common protocol.

 

 

 

Description - A common protocol will be defined as part of the final
recommendation.  It will be built upon some TBD existing application
layer protocol and include support for the following:

 

  * Streaming audio data (e.g. HTTP 1.1 chunking).  This include both
audio streamed from UA to SS during recognition and audio streamed from
SS to UA during synthesis.

 

  * Bidirectional events which can occur anytime during the interaction.
These events could originate either within the web app (e.g. click) or
the SS (e.g. start-of-speech or mark) and must be transmitted through
the UA in a timely fashion.  The set of events include both standard
events defined by the final recommendation and extension events.

 

  * Both standard and extension parameters passed from the web app to
the speech service at the start of the interaction.  List of standard
parameters TBD.

 

  * EMMA results passed from the SS to the web app.  The syntax of this
result is TBD (e.g. XML and/or JSON).

 

  * At least one standard audio codec.  UAs are permitted to advertise
alternate codecs at the start of the interaction and SSs are allowed to
select any such alternate (e.g. HTTP Accept).

 

  * Transport layer security (e.g. HTTPS) if requested by the web app.

 

  * Session identifier that could be used to form continuity across
multiple interactions (e.g. HTTP cookies).

 

  * Interpretation over text.

 

  * Re-recognition using previous audio streams.

 

 

 

Thank you
