1. Lokutor
The vendor describes a five-stage pipeline — noise suppression, turn-taking, speech-to-text, LLM, and speech synthesis — where every stage except the LLM runs on Lokutor's own CPU models. The stated first-audio latency is approximately 120 ms in streaming mode and roughly 0.9 seconds to first reply on a 4-vCPU node. Turn-taking is handled by Turno, which the docs describe as semantic rather than silence-timer-based, so a filler 'mm-hmm' does not cut the agent off. Self-hosting is confirmed via a Go-based orchestrator with install instructions on GitHub. The LLM slot is yours to fill — Lokutor does not supply the language model, which means you control that cost and that compliance boundary, but you also wire it yourself.

2. Speech to Speech
The pipeline chains VAD → STT → LLM → TTS into a single installable Python package, with every slot independently swappable. The LLM layer speaks OpenAI-compatible protocols, so you can point it at a hosted provider or redirect it to a local vLLM or llama.cpp server without touching the rest of the stack. It exposes an OpenAI Realtime-compatible WebSocket API, which means clients built against that spec drop in without rewrites. The ceiling appears when you push toward production-grade reliability: 77 open issues in the repo signal active rough edges, and teams requiring guaranteed latency SLAs or enterprise support find precious little to stand on here.

3. Voiser AI
Voiser AI converts text to speech and speech to text across a wide language roster, targeting e-learning producers, YouTubers, and marketing teams who need narration at volume without per-voice licensing fees. The vendor states on-premise installation is available for enterprise deployments, which matters when your legal team objects to sending training scripts to a cloud API. The free tier covers a capped character allowance — enough for testing a voice against your script, not enough for a full course rollout. Voice consistency across long-form projects is the known ceiling: community reports suggest subtle tone shifts across separate generation jobs, which is tolerable for a YouTube intro but audible in a chapter-by-chapter audiobook where the listener expects one continuous narrator.
