## When NOT to use TTS

- Last GitHub push was 975 days ago (dormant maintenance, Nov 9, 2023). Validate activity before betting a new project on TTS.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

## Common questions

### What are the best alternatives to TTS?

Graph-backed alternatives to TTS include faster-whisper, GPT-SoVITS, MockingBird, transformers, TTS. GraphCanon ranks them by typed relationship edges and constraint overlap from decision_facts - not marketing votes or raw star sort.

### How does GraphCanon rank TTS alternatives?

Direct alternative and successor edges from the knowledge graph come first, ordered by edge type and shared constraint facets (persona, runtime, hosting). Category neighbours fill the list only after curated edges. Stars are shown for context, not as the primary sort.

### When should I avoid TTS?

Last GitHub push was 975 days ago (dormant maintenance, Nov 9, 2023). Validate activity before betting a new project on TTS. Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

### Is TTS open source?

Yes. TTS is an open-source project on GitHub under the MPL-2.0 license, with 10,159 stars.

### What is TTS used for?

:robot: :speech_balloon: Deep learning for Text to Speech (Discussion forum: https://discourse.mozilla.org/c/tts)

### What category is TTS in?

TTS is categorized under Model Training, Speech & Audio in the GraphCanon knowledge graph.

### How do TTS alternatives compare head-to-head?

Each alternative has a neutral compare page against TTS, for example [faster-whisper vs TTS](/compare/mozilla-tts-vs-systran-faster-whisper), [GPT-SoVITS vs TTS](/compare/mozilla-tts-vs-rvc-boss-gpt-sovits), [MockingBird vs TTS](/compare/babysor-mockingbird-vs-mozilla-tts). Stats come from live GitHub metadata.

### Is there a machine-readable alternatives list?

Yes. The markdown twin at [TTS alternatives](/tools/mozilla-tts/alternatives.md) lists direct alternatives and same-category tools with internal links to each tool markdown page.

### Where are other high-intent alternatives hubs?

Related P0 OSS-vs-OSS hubs: [LangChain alternatives](/tools/langchain-ai-langchain/alternatives), [LlamaIndex alternatives](/tools/run-llama-llama-index/alternatives), [Qdrant alternatives](/tools/qdrant-qdrant/alternatives). Vector-database intent (including Pinecone-style queries) is covered at [Qdrant alternatives](/tools/qdrant-qdrant/alternatives).

### Where can I see maintenance and security signals for TTS?

GraphCanon publishes a sourced trust report for TTS at [TTS trust report](/tools/mozilla-tts/trust) - maintenance posture, fork provenance, and dependency/MCP scan status with methodology tags. Not a safety grade.
