ovos-skill-wolfie

This is a Wolfram Alpha skill for OpenVoiceOS. It adds a voice interface on top of OpenVoiceOS/ovos-wolfram-alpha-plugin, which sends the queries to Wolfram Alpha and returns the answers.

The skill answers in three ways:

• Explicit intent: this skill handles utterances that name Wolfram Alpha directly, for example "ask the wolf what is the speed of light".
• Common Query: the OVOS Common Query pipeline handles general knowledge questions, for example "how tall is Mount Everest?". The pipeline asks all registered knowledge skills and picks the highest-confidence answer.
• Fallback: if no intent or pipeline handler answers, Wolfram Alpha gets a last chance to respond before OVOS says "I don't understand".

Installation

pip install ovos-skill-wolfie

An API key is required. Configure it in the skill settings:

{
  "appid": "YOUR-WOLFRAM-API-KEY"
}

Explicit intent utterances

These always route to this skill because they name Wolfram or "the wolf" explicitly:

• "Ask the wolf what is the speed of light"
• "Ask Wolfram Alpha about the population of Japan"
• "Search Wolfram for the boiling point of ethanol"
• "What does Wolfram say about the Eiffel Tower?"

Common Query utterances

These go through the pipeline. Wolfram answers if it wins:

• "How tall is Mount Everest?"
• "What's 18 times 4?"
• "How many inches in a meter?"
• "When was The Rocky Horror Picture Show released?"
• "What is Madonna's real name?"

Common Query pipeline

When the Common Query pipeline plugin is active, this skill competes against other knowledge skills, for example Wikipedia and WordNet, to answer general questions. The pipeline picks the response with the highest confidence score.

---

Fallback

This skill also registers as a fallback handler at priority 91. If no intent or pipeline handler answers an utterance, Wolfram Alpha gets a last chance to respond before OVOS says "I don't know".
