With OpenReader, any EPUB, PDF, Word document, Markdown file, or plain text book transforms into an interactive reading workspace paired with natural text-to-speech playback and multi-chapter audiobook export. Documents render natively in their original page layout rather than flattening into plain text, using layout-aware block detection and cross-page stitching so multi-column academic papers, technical manuals, and textbooks flow in the right reading order while skipping headers and footnotes. As narration plays, word-level forced alignment highlights each spoken word directly on the page in real time, and progressive background generation starts audio playback on the first segment while synthesizing upcoming pages ahead of your cursor. Readers can connect local speech engines such as Kokoro, KittenTTS, and Orpheus or cloud voice providers, select language-aware voices for multilingual books, adjust playback speed, and switch among thirteen light and dark reading themes. Cached audio segments persist across seeks and browser reloads, allowing the background worker to assemble complete M4B or MP3 audiobooks for offline listening on mobile devices while syncing reading progress, queues, and library imports across sessions.

With 26,000 GitHub stars and consistent victories over ElevenLabs in blind evaluations, Chatterbox delivers state-of-the-art text-to-speech with zero-shot voice cloning requiring only 5 seconds of reference audio. The model family spans three architectures: Chatterbox Multilingual V3 (500M parameters, 23+ languages including Arabic, Chinese, Japanese, Korean, Hindi, French, German, Spanish, and Portuguese), Chatterbox-Turbo (350M parameters optimized for voice agents with a single-step distilled decoder achieving ~200ms time-to-first-speech), and Chatterbox-Nano (110M parameters running 3x faster than realtime on 8 CPU cores for edge deployment). Unique among open-source TTS systems, Chatterbox introduces emotion exaggeration control — adjusting intensity from monotone to dramatically expressive via a single parameter — and native paralinguistic tagging where tokens like [laugh], [cough], [chuckle], and [gasp] inject natural vocal reactions inline without post-processing. The alignment-informed inference pipeline eliminates hallucinations and repetition artifacts common in autoregressive TTS. Built-in PerTh neural watermarking embeds imperceptible forensic identifiers in generated audio for provenance tracking. Trained on 500,000 hours of cleaned speech data across all supported languages. Voice conversion scripts enable transforming existing audio into any cloned voice. Deploy via pip install with PyTorch, serve through Gradio interfaces or custom FastAPI endpoints, and expose via HTTP streaming or WebSocket for sub-200ms conversational applications.

Kokoro-FastAPI turns text into natural-sounding speech across eight languages by serving the 82-million-parameter Kokoro-82M model through an OpenAI-compatible REST API, so any existing OpenAI SDK client can generate audio by just changing the base URL. With over 5,300 GitHub stars since December 2024, the fully Dockerized FastAPI server covers American English, British English, Spanish, French, Hindi, Italian, Japanese, Brazilian Portuguese, and Mandarin Chinese with language-specific phoneme processing. Inline voice mixing blends multiple profiles using weighted ratios like af_bella(2)+af_heart(1), automatically normalizing weights and caching combined voicepacks as PyTorch tensor files for reuse. Audio streams in real time over HTTP with configurable chunk sizes, or generates complete files in MP3, WAV, OPUS, FLAC, AAC, or PCM formats with speed control from 0.25x to 4.0x. Per-word timestamped captions with speaker-tagged voice labels enable subtitle generation for podcasts, audiobooks, and accessibility workflows. Pre-built Docker images support NVIDIA GPU acceleration via CUDA, experimental AMD GPU inference via ROCm, and CPU-only deployment on linux/amd64 and linux/arm64 architectures, with Apple Silicon MPS support available through direct UV execution. The integrated web interface at port 8880 provides browser-based speech generation, while the Swagger UI at /docs exposes the full API reference. Debug endpoints report system statistics for monitoring inference load. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Instead of manually hunting through indexers and stitching chapter files together, ReadMeABook automates the entire audiobook request, download, and M4B library organization pipeline for Audiobookshelf and Plex. Users search an Audible-backed catalog by title, author, narrator, or series, inspect full book summaries with runtime and publisher metadata, and submit one-click requests from a clean browser portal. Once approved, the engine queries Prowlarr across torrent and Usenet indexers, dispatches releases to qBittorrent or SABnzbd, and monitors download progress until completion. Multi-file MP3 downloads merge automatically into a single chapterized M4B audiobook via FFmpeg, complete with embedded cover art, narrator tags, and series ordering metadata before triggering a media server library scan. Not sure what to listen to next? BookDate pairs OpenAI, Anthropic Claude, or local LLM endpoints with a swipeable card deck that learns your reading tastes and queues new titles with a single swipe right. Optional e-book sidecar fetching grabs companion EPUB or PDF files alongside audio releases, while multi-user approval queues, OIDC single sign-on, Goodreads shelf syncing, and Discord, Pushover, Apprise, or ntfy notifications keep household libraries running smoothly.

One library for the books you read and the books you listen to: Chaptarr manages audiobooks and eBooks side by side, so the same title can live on your server as a chaptered M4B and an EPUB without two separate apps fighting over it. It knows the difference between editions and narrators, which means a dramatized production, an unabridged reading, and the print text can coexist as first-class versions of one work. Multi-part releases and multi-file recordings are handled as single books, and MP3 audiobooks can be converted into one chaptered M4B with chapters preserved or inserted where they are missing. Separate root folders keep audiobooks and eBooks apart, or place eBooks alongside their audio twins; either way, matching uses file tags, folder names, and release metadata to attach files to the right book automatically. Series are organized for you, metadata profiles control which languages belong in your library, and flexible renaming tokens produce filenames that read the same way a human would shelve them. Custom quality profiles per library drive automatic upgrades when a better release appears, and the standard download clients and indexer integrations from the *arr family plug straight in.

ScribeCrate is a self-hosted speech-to-text API that turns recordings into transcripts, subtitles, and English translations on your own server. It speaks the OpenAI Whisper API fluently: point any compatible client at your server's address, swap in your API key, and uploads come back as text. Ask for plain text, JSON with timestamps, or ready-to-publish SRT and WebVTT subtitle files, and for long recordings the segments can stream back over SSE as they are decoded. Turn on speaker diarization and every segment is labeled with who is speaking, which makes interview and meeting transcripts readable at a glance. Choose the model that fits the job, from tiny for quick drafts to large-v3 for maximum accuracy, and run it on a modest CPU, a Raspberry Pi class ARM board, or an NVIDIA GPU. Almost any recording works: MP3, M4A, WAV, WebM, OGG, and FLAC are all accepted, and with models cached in advance the server keeps transcribing with no internet connection at all.
