EmotiVoice 😊: a Multi-Voice and Prompt-Controlled TTS Engine

What it solves

EmotiVoice addresses the lack of emotional expression and voice variety in standard text-to-speech (TTS) systems. It allows users to generate natural-sounding speech in English and Chinese that can be specifically controlled for emotion (such as happiness, sadness, or anger) and speaker identity.

How it works

The engine uses a prompt-controlled architecture based on PromptTTS, allowing users to specify a speaker and an emotion/style prompt to guide the synthesis. It supports over 2,000 different voices and can be deployed via a web interface, a scripting interface for batch processing, or an OpenAI-compatible HTTP API. It also supports voice cloning using personal data.

Who it’s for

This tool is designed for developers and creators who need high-quality, emotionally expressive synthetic speech for applications, as well as users who want to customize voice identities or clone their own voice.

Highlights

  • Emotional Synthesis: Ability to generate speech with specific emotions like happy, excited, sad, and angry.
  • Massive Voice Library: Access to over 2,000 distinct voices.
  • Bilingual Support: Full support for both English and Chinese.
  • Flexible Deployment: Available as a Docker image, a standalone Mac app, or an OpenAI-compatible API.
  • Voice Cloning: Capability to train the model on personal data to clone specific voices.

    trailhq/Graft

    Graft is an open‑source TypeScript/Node.js tool that builds a local, markdown‑based knowledge graph of a codebase (summaries, key snippets, typed links) using tree‑sitter for structural parsing and optional LLM summarisation. The graph is cached in a `graft/` folder, refreshed only on file changes, and automatically wired into coding agents like Claude Code, Cursor, Codex, and Gemini. Benchmarks claim up to 46 % fewer tool calls, 42 % token savings, 60 % latency reduction, and a 12‑point correctness boost on SWE‑bench. Integration is via a single `graft init` command that writes agent‑specific instruction files; the CLI also offers search, visualization, and telemetry controls. The project is MIT‑licensed and targets faster, cheaper AI‑assisted development.

    xiaobei (小贝) is an AI‑powered personal assistant for Chinese self‑media operators. Built on the open‑source **openclaw** framework, it lets users create, format, and publish articles, images, and short videos across platforms (WeChat, Xiaohongshu, Douyin, Twitter, etc.) via a simple WeChat chat. It also offers trend analysis, performance monitoring, 24/7 AI customer service, market‑research search, and business‑document generation. Installation is a one‑line script that downloads a pre‑built tarball; after scanning a QR code the bot is ready. The system runs on Ubuntu/macOS/Windows, uses Alibaba Bailei large‑model APIs (or alternatives), and includes a custom anti‑detect browser stack (camoufox) for reliable automation. Optional paid “VIP Club” adds premium support and services.
