The Voice Company of SF

The Voice Company of SF (SF Voice Company) is a San Francisco-based startup that builds voice AI infrastructure and tooling for developers and enterprises. Its first product is a semantic search engine for audio and video media that allows teams to search recordings by topic, objection, feature request, or behavioral pattern — for example, identifying where callers became impatient, where an AI agent interrupted a caller, or where content appears within video even when no one is speaking. The platform indexes media by generating transcripts, embeddings, and metadata, then makes the searchable representation available via API and six open-source SDKs. Source files are not retained after indexing, with regional processing in the US for US customers and in Europe for EU/UK customers. Use cases include compliance review, QA workflows, and knowledge base construction on audio or video archives. The company publishes its core SDK as open source at github.com/sf-voice/sf-voice-core and is expanding into benchmarking and tooling for voice AI systems.
