System Overview

What it is: A Slack integrated voice assistant built in Voiceflow that allows team members to query Notion for information, update Airtable records, and book meetings directly via Google Calendar - all using voice commands.

Core capabilities

  • Voice-driven access to internal knowledge bases and data
  • Real-time Notion database queries for SOPs, project info, or documentation
  • Airtable integration for updating records, task statuses, or inventory
  • Automated meeting scheduling via Google Calendar API
  • Slack integration for voice input and output within the team workspace
  • Role-based permissions for sensitive actions
  • Logging and analytics for usage tracking

Business problems solved

  • Reduce time spent searching for information or updating tools manually
  • Eliminate context switching between multiple apps
  • Make internal data and scheduling accessible by simple voice prompts
  • Speed up meeting booking and task updates for busy teams

Industries served : Technology companies, agencies, internal ops teams, customer support teams, project management offices.

If your industry isn’t listed, chances are the framework still applies - we just tweak the integrations. We can validate this for you in a quick consult.

Actor Identification

Primary actor: Internal team member issuing voice commands via Slack or connected device.

Secondary actors: Voiceflow assistant, Notion workspace, Airtable database, Google Calendar, Slack workspace, authentication service.

Actor Goals

Team Member: Get information, update records, or schedule meetings quickly without opening multiple apps.

Operations Manager: Keep internal tools up-to-date and ensure staff follow streamlined workflows.

Voice Assistant: Correctly interpret commands, query/update the right system, and confirm the action.

Internal Systems: Maintain data accuracy, avoid scheduling conflicts, and log all actions for review.

If your team already uses Slack, you’re 80% of the way there - we just need to connect the dots. Let’s explore the workflow that would save you the most time first.

Context and Preconditions

  • Voiceflow assistant integrated with Slack via API
  • Notion and Airtable accounts connected with read/write permissions
  • Google Calendar API enabled for event creation and conflict detection
  • Authentication set up to ensure only authorized users can run certain commands
  • Predefined command templates in Voiceflow for common queries and updates

Basic Flow (Successful Scenario)

  • Team member sends a voice command in Slack: “Check the latest project deadline in Notion.”
  • Voiceflow parses the command and queries the Notion database.
  • Assistant responds in Slack with the deadline and related task status.
  • Team member says: “Update Airtable - mark Task 14 as complete.”
  • Voiceflow updates the Airtable record and confirms the change in Slack.
  • Team member says: “Book a meeting with Sarah and Tom next Tuesday at 3 PM.”
  • Voiceflow checks Google Calendar for conflicts, books the meeting, and sends invites.

Outcome: Team member completes multiple internal tasks hands-free within Slack, with all actions logged and confirmed.

We can build your first working voice command in under a day - so you can test the impact without committing to a full rollout.

Alternate Flows

  • A1: Ambiguous query - If the assistant cannot find a matching record or project, it asks the user for clarification before proceeding.
  • A2: Permission restriction - If the user does not have rights to edit a record, the assistant denies the action and notifies the manager.
  • A3: Scheduling conflict - If Google Calendar detects a conflict, the assistant suggests the next available time slot.
  • A4: API timeout - If Notion, Airtable, or Google Calendar does not respond, the assistant retries and informs the user of the delay.

Your team already talks in Slack - now imagine if Slack could talk back and take action instantly. Let’s prototype your most common internal requests and turn them into voice commands this week
