play:query.response

There are three responses to a play:query. These are not intended to be consumed directly by a Skill, see the methods available in the CommonPlaySkill Class.

Confirm Search

The initial response confirms that a search is being attempted. It also extends the Skill timeout while it looks for a match.

Data:

{
  "phrase": search_phrase,
  "skill_id": self.skill_id,
  "searching": True
}

Search Result

Emitted if a result is found. Responses from the Play services must be received within 1 second to be included.

Data:

{
    "phrase": phrase,
    "skill_id":  self.skill_id,
    "callback_data": data,
    "service_name": self.spoken_name,
    "conf": confidence
}

phrase - the phrase that was queried for this response
id - uniquely identifies the skill, normally the Skill's self.skill_id
callback_data - optional data structure to return in play:start
service_name - the name of the service returning the highest confidence in a speakable format
conf - the confidence it can handle the request, between 0.0 and 1.0

Confidence guidelines:

1.0 = exact command match, e.g. "play npr news"
>0.9 = multi-key match for database entry, e.g. "play madonna's lucky star" or "play artist madona" (matches "artist" and "madonna"). For each additional key over 2, add 0.1 to the confidence, so "play madonna's lucky star on spotify" would be 0.91 for three keywords
>0.8 = single-key match for database title entry, e.g. "play lucky star"
>0.7 = single-key match for database artist or group, e.g. "play madonna"
>0.6 = single-key match for database genre or category, e.g. "play reggae"
>0.5 = generic match, e.g. "play some music" or "play a movie"

Search Failed

No suitable result was found.

Data:

{
  "phrase": search_phrase,
  "skill_id": self.skill_id,
  "searching": False
}

play:start

skill_id -- the unique ID of the skill that is being invoked
phrase -- the original phrase user said, e.g. "some thing" from utterance "play some thing"
callback_data -- (optional) data the skill can use to start playback

Data:

{
    "skill_id": <skill_id>,
     "phrase": phrase,
     "callback_data": optional_data
}

question:query.response

skill_id -- the unique ID of the skill that is being invoked
phrase -- the original phrase user said, e.g. "some thing" from utterance "how tall was abraham lincoln"

searching -- true if more time is needed to complete the search, otherwise false

Data:

    "phrase": phrase,
    "skill_id": <skill_id>,
    "answer": "answer string",
    "conf": confidence,
    "callback_data": <json data>,
    "searching": true/false
