ovos-workshop's Issues

PHAL and admin PHAL failures to successfully initialize started evening of Jul 13

This may or may not be related to recent changes in OVOS-workshop. Problems seen while testing headless raspbian build.

Proposal: adding metadata to dialog files

Problems being solved

  • 1 - in some languages TTS utterances may depend on the gender of the person listening
  • 2 - in some languages TTS utterances may depend on the gender of the speaker
    • eg. in portuguese you there is no gender neutral way to say "thank you", you say "obrigado"/"obrigada"
    • this would be a setting of the voice assistant
  • 3 - personality settings
    • "increase sarcasm by 20%"

Dialog Json

New file format, .jsonl, where each line in the file contains a json of the format

{"utterance": "XXX", "attitude": "sarcastic", "assistant_gender": "male", "listener_gender": "male", "weight": 0.3}

jsonl format info: https://jsonlines.org

Personality Settings

in mycroft.conf users can tweak personality

weights reflect how likely a dialog is to be selected

"persona": {
    "gender": "male",
    "attitudes": {
        "normal": 10,
        "flippant": 8.0,
        "funny": 8.0,
        "irritable": 0
      }
}

How it works

  • 1 - load .jsonl file if it exists, else old .dialog file
  • 2 - filter samples per assistant gender
  • 3 - select an attitude based on weights defined in mycroft.conf
  • 4 - filter samples per attitudes
  • 5 - select based on weights of .jsonl file

OVOSSkill full CRUD for events

Currently, there is no way to list existing events from the OVOSSkill methods. Once the feature exists in ovos-bus-client, the helper methods should be added to the base class

SkillResources: add method to create resource/intent test yaml files

To curb the time spent to define (and maintain) the test files, this should be automated (as a part of CI/CD)

test_resources.yml

languages:
  - "en-us"
  # - ...

# below files taken from en-us
vocab:
  - HelloKeyword
  - NoKeyword
  - YesKeyword
  - ThankYouKeyword
  - WorldKeyword

dialog:
  - hello_world
  - how_are_you
  - welcome

regex: []

intents:
  padatious:
    -HowAreYou.intent
  
  adapt:
    - HelloWorldIntent
    - YesNoIntent

test_intents.yaml

en-us:
  HelloWorldIntent:
    - hello world
  HowAreYou.intent:
    - how have you been
  YesNoIntent:
    - yes world
    - no world
 
# xx-xx:
#  ...

unmatched intents:  # this has to be manually added ofc
  en-us:
    - hello there everyone
    - what is this

handle file change errors in logs

Not exactly sure which repo to open this in, but this seemed maybe the best?

I have this error

TypeError: _handle_filechange() takes 1 positional argument but 2 were given

Whenever I make a change to my manually installed skills. Digging around, I think it's because this is invoking the callback with the changed file path, but the callback being passed in doesn't take an argument

BaseSkill.schedule_repeating_event has wrong type annotation

OVOS-workshop/ovos_workshop/skills/base.py

Lines 2062 to 2087 in e8540c0

def schedule_repeating_event(self, handler: callable,
when: Union[int, float, datetime.datetime],
frequency: Union[int, float],
data: Optional[dict] = None,
name: Optional[str] = None,
context: Optional[dict] = None):
"""
Schedule a repeating event.
Args:
handler: method to be called
when (datetime): time (in system timezone) for first
calling the handler, or None to
initially trigger <frequency> seconds
from now
frequency (float/int): time in seconds between calls
data (dict, optional): data to send when the handler is called
name (str, optional): reference name, must be unique
context (dict, optional): context (dict, optional): message
context to send when the handler
is called
"""
message = dig_for_message()
context = context or message.context if message else {}
context["skill_id"] = self.skill_id
self.event_scheduler.schedule_repeating_event(handler, when, frequency,

The type annotation for when should be Optional[Union[int, float, datetime.datetime]] because, as per the comment, it is valid to pass None to initially trigger frequency seconds from now

You get the type error:

Argument of type "None" cannot be assigned to parameter "when" of type "int | float | datetime" in function "schedule_repeating_event"

MessageBusClient compat

BaseSkill.bus setter checks for FakeBus or ovos-bus-client.MessageBusClient instances but fails to validate mycroft-bus-client.MessageBusClient instances. Maybe this can check against the super class of ovos-bus-client.MessageBusClient?

When core restart, the skill returns an error

When running skill as standalone, with the core is restarted then a trace is generated inside the skill log.

feat - verbosity level

i propose adding a new concept of VerbosityLevel

this would correspond to a integer from 0 - 10, added to Session

  • 0 corresponds to the default, it means a skill should speak only essential messages
  • 10 corresponds to the skill speaking a lot, ideally explaining everything it is doing along the way

a skill would check for self.verbosity_level (session aware) and conditionally speak more messages, backwards compat is retained

if self.verbosity_level > 3:
    self.speak("extra info")
if self.verbosity_level >= 9:
    self.speak("extra very redundant info")

using session allows verbosity level to be set per client (such as hivemind voice satellites), the default value would come from mycroft.conf as usual. a companion skill can also be made to control this by voice

FallbackSkill `__new__()` fails for FallbackSkillV1

When creating a FallbackSkill under ovos-core 0.0.7, the follosing exception is raised and the skill is not created:

cls = <class 'skill_fallback_llm.LLMSkill'>, args = ()

settings changed decorator

we should add a decorator for skill settings, instead of the current way

    def initialize(self):
        self.settings_change_callback = self.on_settings_changed

this would make the code more readable and help avoiding user mistakes (such as assigning the callback before the call to super)

feat - "local_only" kwarg in intent decorators

i propose adding a new kwarg to the intent decorators, allowing to signal an intent as local only

this means the intent only triggers if session_id == "default", but won't work if coming from a voice satellite

this way we can add extra "local only" functionality or in case of TODOS allows to keep the intents around until they are expanded to support voice satellites

missing tests for conversational intents

tests for #12

from ovos_utils.fakebus import FakeBus, Message
from ovos_workshop.decorators import intent_handler, conversational_intent
from ovos_workshop.skills import OVOSSkill


class DogFactsSkill(OVOSSkill):

    @intent_handler("dog_facts.intent")
    def handle_intent(self, message):
        fact = "Dogs sense of smell is estimated to be 100,000 times more sensitive than humans"
        self.speak(fact)

    @conversational_intent("another_one.intent")
    def handle_followup_question(self, message):
        fact2 = "Dogs have a unique nose print,  making each one distinct and identifiable."
        self.speak(fact2)


if __name__ == "__main__":
    s = DogFactsSkill(skill_id="test", bus=FakeBus())

    r = s.converse_matchers["en-us"].calc_intent("another one")
    print(r)  # {'entities': {}, 'conf': 1, 'name': 'test.converse:another_one.intent'}

    m = Message(f"test.converse.request", {"utterances": ["one more"]})


    def handle_speak(m):
        print(m.data)

Add helper function `voc_list` to the OvosSkill class

We need access to a vocabulary list (for instance to match_one, ...)

Proposal:

def voc_list(self, voc_filename, lang=None):
        """ returns the vocabulary list of a given term"""
        lang = lang or self.lang
        cache_key = lang + voc_filename

        if cache_key not in self.voc_match_cache:
            self.voc_match("", voc_filename, lang)

        return self.voc_match_cache.get(cache_key) or []
