## Speko

The core idea is that no single speech model wins everywhere. Speko's benchmark shows six different models taking the top spot across 18 languages, and notes that a large share of models are only ever measured in English, leaving their ranking in other languages unknown. Instead of committing to one vendor, Speko routes each stage of a voice pipeline — STT, LLM and TTS — to whichever model performs best for the language your users actually speak, with measured selection and failover before the response starts.

Two commercial shapes are offered. On Speko infrastructure you pay a single bundled rate of $0.09 per minute covering all three legs. Alternatively, managed routing adds 5% on top of a provider's published rate and lets you use your own provider keys, in which case the provider bills you directly. The router is hosted at router.speko.dev with typed contracts and public OpenAPI and AsyncAPI documentation.

The platform layer targets teams that need working phone agents, not just model access. You can map a call step by step, connect calendars, CRMs, your own APIs and documentation into any step, buy a phone number, test drafts against simulated callers including adversarial ones, and score every live call against checks you write in plain language. Native integrations exist for LiveKit and Pipecat, and an MCP server exposes Speko to Claude, ChatGPT, Grok, Cursor and Claude Code. Speko states it is backed by Y Combinator and that new accounts receive $10 in credit.

**Pricing & Plans:** Two models. On Speko infrastructure, a flat $0.09 per minute bundles STT, LLM and TTS; calls bill from answer to hang-up and unanswered calls cost nothing. With managed routing, you pay the selected provider's published rate plus 5%. $10 in signup credit applies to every account. Phone numbers cost $1 setup and $2 per month for most numbers, and calls on Speko numbers add the carrier charge plus 20%.

- **Language-aware model routing:** STT, LLM and TTS are selected per language based on an independent benchmark covering 89 models across 18 languages, with pre-response failover.
- **Voice agent platform:** Design a call step by step, plug calendars, CRMs, your APIs and docs into any step, then run it with inbound, outbound and call-list support.
- **Simulated caller testing:** Draft agents are tested against simulated callers, including red-team scenarios that try to break the flow, before they go live.
- **Plain-language call scoring:** Every live call is scored against checks you write in everyday language, for example reading back a date or never quoting a price.
- **Framework and MCP integrations:** Native Gateway services for LiveKit and Pipecat, plus an MCP server for Claude, ChatGPT, Grok, Cursor and Claude Code.

**Strengths:** Independent, language-by-language benchmark rather than a single accuracy claim; Provider-neutral routing with the option to bring your own keys; Clear, simple pricing: $0.09 per minute bundled or 5% on routed provider spend; Agent platform includes phone numbers, evaluation and live call monitoring

**Limitations:** Public preview with no SLA and email-only support outside enterprise; The benchmark and model catalogue move quickly, so routing decisions need periodic review; Telephony costs sit on top of the per-minute rate, and international routes can exceed the US minimum

## Vocode

Vocode is aimed at engineering teams that want voice agents rather than a no-code voice bot builder. The open-source Vocode Core provides the hard parts of a voice pipeline as reusable pieces: conversation abstractions for streaming or turn-based dialogue, endpointing, emotion tracking, and adapters for a wide range of speech-to-text and text-to-speech providers. Because provider choices are pluggable, you can start with one mix of models and voices and re-tune later without rebuilding the call logic.

The companion Vocode API extends that foundation to actual telephony. Through REST endpoints for numbers, calls, agents, prompts, voices, actions, webhooks and vector databases, a backend can buy a number, attach an agent, place or receive a call, and then fetch transcripts, recordings and usage records. Webhooks let the agent hand control back to your application when a caller says something important, and actions let the agent perform concrete tasks such as warm transfers or external lookups.

In practice this positions Vocode as infrastructure for an AI call center or a voice layer inside an existing product. It suits teams that are comfortable writing Python or TypeScript and want full control over prompts, vendors and data flow, and less suited to people who want a finished drag-and-drop call flow designer.

**Pricing & Plans:** Dual model: Vocode Core is open source and free to self-host under the MIT license. The hosted Vocode API has historically been usage-based, charging around telephony numbers and call minutes, with a free trial to test outbound and inbound calling and enterprise plans that unlock capabilities such as bring-your-own telephony and bring-your-own OpenAI keys. Vocode does not publish a fixed, detailed public price list for the managed tier, and the dedicated dashboard subdomain did not resolve during our latest audit, so confirm current plans, rates and service status directly with the vendor before budgeting.

- **Provider-agnostic voice stack:** Abstracts speech-to-text, text-to-speech and LLM calls so you can swap vendors such as different STT, TTS and language model providers without rewriting your call flow.
- **Programmable telephony API:** Handles inbound and outbound phone calls with number provisioning, call creation, recording retrieval and CDR-style usage endpoints exposed through a documented REST API.
- **Webhooks and agent actions:** Register webhooks and self-contained actions so an agent can look things up, transfer a caller, or trigger work in your backend mid-conversation.
- **Streaming and turn-based conversations:** Supports streaming or turn-based conversation modes, endpointing and emotion tracking, plus browser and meeting-based interfaces beyond pure telephony.
- **Python and Node SDKs:** Python and Node SDKs sit on top of a FastAPI-style REST interface, letting you prototype in a notebook and ship the same agent in production services.

**Strengths:** Open source core under the MIT license gives full visibility into the voice pipeline and lets you self-host; Vendor-agnostic design makes it easy to swap speech-to-text, text-to-speech and LLM providers; One abstraction spans telephony, browser and meeting-based voice experiences; Well-documented REST API plus Python and Node SDKs shorten integration time for backend teams

**Limitations:** The hosted dashboard subdomain (dashboard.vocode.dev) did not resolve during this audit, so teams relying on the managed console should verify current availability before committing; Repository activity slowed after late 2024, so self-hosters should check issue responsiveness and dependency freshness; Bring-your-own-telephony and bring-your-own-OpenAI-key options are gated behind an enterprise tier; No public, transparent price list is published for the hosted API, which makes budgeting harder without a sales conversation
