Description
Text-to-speech conversion using node-edge-tts npm package for generating audio from text.
Supports multiple voices, languages, speed adjustment, pitch control, and subtitle generation.
Use when: (1) User requests audio/voice output with the "tts" trigger or keyword. (2) Content needs to be spoken rather than read (multitasking, accessibility, driving, cooking). (3) User wants a specific voice, speed, pitch, or format for TTS output.
Usage Guidance
Install only if you are comfortable sending TTS text to Microsoft's online service and running npm dependencies. Avoid using this skill on sensitive text, avoid unpinned npx examples, keep output paths in a dedicated folder, and do not use custom --config-path or --reset unless you have checked the target path.
Capability Analysis
Type: OpenClaw Skill
Name: edge-tts
Version: 2.0.0
The OpenClaw Edge-TTS skill is designed for text-to-speech conversion using the `node-edge-tts` npm package. All analyzed files, including `SKILL.md`, `install.sh`, `tts-converter.js`, and `config-manager.js`, demonstrate behavior strictly aligned with this stated purpose. File system operations are limited to creating temporary audio files in the system's temp directory and managing a user-specific configuration file (`~/.tts-config.json`). Network access is solely for connecting to the legitimate Microsoft Edge TTS service. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or prompt injection attempts against the agent to perform unauthorized actions. The skill's capabilities are appropriate for its function.
Capability Assessment
Credentials
The converter accepts arbitrary output paths without containment or overwrite checks, and temporary audio/subtitle files are kept in a shared predictable temp directory with no automatic cleanup.
Install Mechanism
Installation runs npm install for registry dependencies, package.json uses semver ranges, package-lock resolves ws 8.19.0, and documentation plus npm test include unpinned npx examples.
Instruction Scope
Activation guidance relies on a broad 'tts' keyword and 'triggers or user request' language, which could cause unintended conversion of text and transmission to the online TTS service.
Persistence & Privilege
Persistent preferences in ~/.tts-config.json are disclosed and purpose-aligned, but --config-path is unrestricted and --reset unlinks that path while suppressing deletion errors.
Purpose & Capability
The artifacts coherently implement Edge TTS conversion, voice options, subtitles, and preference management; the config manager is disclosed in SKILL.md and is purpose-related.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install edge-tts - After installation, invoke the skill by name or use
/edge-tts - Provide required inputs per the skill's parameter spec and get structured output
