Voice Command to Skill

Overview

voice_command_to_skill is the voice-to-action bridge of the LabOS anywhere-lab stack. It takes natural language speech — transcribed by an ASR engine (Whisper, Azure Speech, Google Cloud) — and maps it to a specific LabClaw skill call with filled parameters. Commands like "check if I added the enzyme", "what's the next step?", "export my data to Excel", or "did I miss any steps?" are parsed into intent, matched to skills (protocol_video_matching, detect_common_wetlab_errors, extract_experiment_data_from_video, etc.), and executed with context-aware parameters. The skill provides prompt templates, parameter extraction logic, and fallback handling so that voice-driven lab workflows remain robust under noisy conditions, ambiguous phrasing, or partial context.

When to Use This Skill

Use this skill when any of the following conditions are present:

• Hands-free lab operation: A researcher is wearing XR glasses or has gloves on and cannot type or tap; they must control the system by voice — "run compliance check", "show me the growth curve", "pause protocol".
• Anywhere-lab / remote supervision: A PI or remote expert monitors a lab via video and issues voice commands to trigger analysis, generate reports, or request status — "extract the OD values from the last hour", "generate the Methods section".
• Training and onboarding: A trainee asks questions by voice — "what do I do next?", "did I do that right?", "explain step 5" — and the system routes to the appropriate skill for response.
• Post-experiment voice recap: After an experiment, the researcher speaks a summary request — "give me a report of what we did" or "check for any errors in the recording" — and the skill invokes report generation or error detection.
• Multi-modal AR interaction: Voice complements gaze, gesture, or touch in an XR lab interface; the skill resolves voice intent and coordinates with other input modalities.
• Accessibility: Researchers with mobility limitations rely on voice as the primary control channel for lab software and analysis pipelines.
• Rapid iteration: During protocol development, the researcher iterates by voice — "try that again with 50 microliters", "skip to step 8" — without breaking flow to use a keyboard.
• Batch command chaining: A single voice command triggers a multi-skill pipeline — "analyze the video and export to Excel" → analyze_lab_video_cell_behavior + export_experiment_data_to_excel.

Core Capabilities

1. Intent Recognition & Skill Mapping

Parses voice command text and maps to target skills:

• Input: Raw ASR transcript (string); optional confidence score, language code, speaker ID
• Intent taxonomy: Predefined intents with associated skills and parameter schemas:

| Intent | Example Phrases | Target Skill(s) | Parameters | |---|---|---|---| | CHECK_COMPLIANCE | "check if I added the enzyme", "did I miss any steps?", "am I on track?" | protocol_video_matching | video_stream, protocol_id | | NEXT_STEP | "what's next?", "next step", "what do I do now?" | realtime_protocol_guidance_prompts | protocol_state, video_context | | DETECT_ERRORS | "any errors?", "check for mistakes", "did I do something wrong?" | detect_common_wetlab_errors | video_stream, mode | | EXTRACT_DATA | "extract the OD values", "get the color data", "read the pipette" | extract_experiment_data_from_video | video_path, extractors | | ANALYZE_CELLS | "analyze the cells", "run cell tracking", "growth curve" | analyze_lab_video_cell_behavior | video_path, assay_type | | GENERATE_CHARTS | "make the charts", "plot the data", "show growth curve" | generate_cell_analysis_charts | json_path, chart_types | | EXPORT_EXCEL | "export to Excel", "save as spreadsheet", "put data in Excel" | export_experiment_data_to_excel | data_source, output_path | | GENERATE_METHODS | "write the Methods", "document what we did", "Methods section" | generate_scientific_method_section | logs, protocol, output_format | | GENERATE_REPORT | "give me a report", "PDF report", "full report" | generate_double_column_pdf_report | title, sections, figures | | PAUSE_PROTOCOL | "pause", "stop guidance", "hold on" | realtime_protocol_guidance_prompts | mode: PAUSE | | RESUME_PROTOCOL | "resume", "continue", "keep going" | realtime_protocol_guidance_prompts | mode: RESUME | | SCENE_DESCRIPTION | "describe the bench", "where is the pipette?", "lab layout" | gaussian_splatting_scene_description | images, output_format | | STATUS | "what's the status?", "where are we?", "current step" | protocol_video_matching | video_stream, protocol_id → summary |

• Fuzzy matching: Handles ASR errors and paraphrases — "check if I add the enzyme" → CHECK_COMPLIANCE; "did I forget the enzyme?" → same
• Confidence threshold: Low-confidence intent triggers clarification prompt: "Did you mean: check compliance, or get next step?"
• Multi-intent: Compound commands — "analyze and export" → chain analyze_lab_video_cell_behavior then export_experiment_data_to_excel

2. Parameter Extraction & Context Filling

Extracts and fills skill parameters from command text and session context:

• Explicit parameters in speech: "extract OD from the last 30 minutes" → time_range_min: 30; "check step 5" → step: 5
• Session context: Maintains a session state (current protocol, video stream, experiment ID, output directory) and injects into parameter templates
• Entity extraction: Reagent names ("enzyme", "buffer", "primer"), step numbers ("step 5", "step seven"), time expressions ("last hour", "past 30 min") — parsed via regex, NER, or LLM
• Default values: When parameters are missing, use session defaults — e.g., video_stream from active XR feed, protocol_id from last loaded protocol
• Prompt template variables: {protocol_id}, {video_stream}, {step}, {reagent}, {time_range}, {output_dir} — filled before skill invocation
• Validation: Rejects invalid combinations (e.g., EXPORT_EXCEL with no data source in session); prompts user: "No analysis data in session. Run cell analysis first?"

3. Prompt Templates for Skill Invocation

Provides ready-to-use prompt strings for each skill:

• Template format: Natural language prompt that the agent uses to invoke the skill — not the skill's internal API, but the user-facing instruction
• Example templates:

| Intent | Prompt Template | Filled Example | |---|---|---| | CHECK_COMPLIANCE | "Check whether the current video matches protocol {protocol_id}. Report any step deviations." | "Check whether the current video matches protocol scratch_v2. Report any step deviations." | | NEXT_STEP | "Generate the next protocol step prompt for the current frame and protocol state." | (no fill; uses live context) | | DETECT_ERRORS | "Scan the video for common wet-lab errors. Output JSON with errors, timestamps, and suggestions." | (no fill) | | EXTRACT_DATA | "Extract {extractors} from video {video_path}. Output timeseries JSON." | "Extract color, volume from video recording.mp4. Output timeseries JSON." | | ANALYZE_CELLS | "Analyze cell behavior in {video_path}. Assay type: {assay_type}. Output structured JSON." | "Analyze cell behavior in scratch.mp4. Assay type: wound_healing. Output structured JSON." | | EXPORT_EXCEL | "Export {data_source} to Excel at {output_path}. Include units and annotations." | "Export results/cell_behavior.json to Excel at exports/data.xlsx. Include units and annotations." | | GENERATE_METHODS | "Generate Methods section from execution logs {logs} and protocol {protocol}. Output LaTeX." | (filled from session) | | GENERATE_REPORT | "Generate double-column PDF report with title {title}, figures {figures}, and methods {methods}." | (filled from session) |

• Fallback template: When intent is ambiguous, use a generic prompt: "The user said: '{transcript}'. Determine the appropriate LabClaw skill and execute with available context."
• TTS response template: After skill execution, format the result for voice reply — "Compliance check complete. 2 deviations found. Step 4 skipped; step 7 wrong volume."

4. Session Context Management

Maintains state across voice interactions for coherent multi-turn dialogs:

• Session variables:
  • active_protocol_id, active_protocol_path
  • video_stream_url, video_file_path, last_video_analyzed
  • experiment_id, output_directory
  • current_step, last_skill_invoked, last_result_summary
• Context persistence: Session survives across commands within a lab session; reset on "new experiment" or explicit "clear context"
• Context injection: Each skill invocation receives relevant session variables as implicit parameters
• Proactive suggestions: When context is rich (e.g., analysis just completed), suggest follow-up: "Analysis done. Say 'export to Excel' to save, or 'generate report' for PDF."

5. Error Handling & Clarification

Handles ambiguous or invalid commands gracefully:

• Unrecognized intent: "I didn't understand. You can say: check compliance, next step, export to Excel, or describe the bench."
• Missing context: "No video is active. Start a recording or load a video file first."
• Skill failure: "The compliance check failed. The video may be too short. Try again with at least 2 minutes of footage."
• Disambiguation: Multiple intents possible — "Did you mean: (1) check if you added the enzyme, or (2) what enzyme to add next?"
• Confirmation for destructive actions: "Export will overwrite exports/data.xlsx. Say 'yes' to confirm, or 'cancel'."
• TTS-optimized error messages: Short, clear, actionable — suitable for voice playback

6. Multi-Language & Accent Robustness

Supports diverse speakers and languages:

• Language detection: Infer language from ASR or explicit "use Spanish" command; map intents in that language
• Intent phrases per language: Spanish — "¿verificaste si agregué la enzima?" → CHECK_COMPLIANCE; Mandarin — "检查我有没有加酶" → same
• Accent and noise: Intent matcher uses fuzzy string matching, synonym expansion, and LLM-based paraphrase handling for accented or noisy ASR
• Code-switching: "Check compliance, por favor" → CHECK_COMPLIANCE (primary language from first phrase)

Usage Examples

Example 1 — "Check if I added the enzyme"

Voice input (ASR): "check if I added the enzyme"

Processing:

→ Intent: CHECK_COMPLIANCE
→ Entity: reagent = "enzyme" (optional filter for step matching)
→ Session context: video_stream = "xr://hololens2/live", protocol_id = "rna_extraction_v3"
→ Skill: protocol_video_matching
→ Prompt: "Check whether the current video matches protocol rna_extraction_v3. Focus on steps involving enzyme addition. Report any deviations."
→ Invoke skill with {video_stream, protocol_id, focus: "enzyme"}
→ Result: "Compliance check complete. Step 5 (add reverse transcriptase) — CONFIRMED. No deviations for enzyme steps."
→ TTS response: "Yes. You added the enzyme correctly in step 5."

Example 2 — "Export to Excel"

Voice input: "export to Excel"

Processing:

→ Intent: EXPORT_EXCEL
→ Session context: last_result = "results/cell_behavior.json" (from prior analyze_lab_video_cell_behavior)
→ Parameter fill: data_source = "results/cell_behavior.json", output_path = "exports/experiment_2026-03-06.xlsx"
→ Skill: export_experiment_data_to_excel
→ Prompt: "Export results/cell_behavior.json to Excel at exports/experiment_2026-03-06.xlsx. Include units and annotation rows."
→ Invoke skill
→ TTS response: "Exported to exports/experiment_2026-03-06.xlsx. Four sheets: Population Metrics, Tracks, Time Series, Phenotype Counts."

---

Example 3 — "What's next?" (Next Step)

Voice input: "what's next?"

Processing:

→ Intent: NEXT_STEP
→ Session context: protocol_state from protocol_video_matching (current step 5, validated)
→ Skill: realtime_protocol_guidance_prompts
→ Prompt: "Generate the next protocol step prompt for current frame and protocol state. Mode: NEXT_STEP."
→ Invoke with live video_context + protocol_state
→ Result: "Step 6: Add 600 µL ethanol."
→ TTS response: "Step 6. Add 600 microliters of ethanol."

---

Example 4 — Compound: "Analyze and export"

Voice input: "analyze the video and export to Excel"

Processing:

→ Multi-intent: [ANALYZE_CELLS, EXPORT_EXCEL]
→ Chain: analyze_lab_video_cell_behavior → export_experiment_data_to_excel
→ Step 1: ANALYZE_CELLS — video_path from session, assay_type inferred or "general"
→ Step 2: EXPORT_EXCEL — data_source = output of step 1
→ TTS response: "Analysis complete. Exported to Excel. Say 'generate report' for a PDF, or 'what's the compliance score?' for details."
