Leadlock
Leadlock is a speech-to-speech voice AI platform built specifically for GoHighLevel agencies, helping them answer every call, qualify leads, book appointments, and update GHL pipelines in real time. Unlike traditional voice AI stacks that chain speech-to-text, an LLM, and text-to-speech, it supports true multimodal speech-to-speech through OpenAI Realtime and Gemini Live, alongside xAI Grok and ElevenLabs options, enabling sub-second latency, natural turn-taking, and interruptions. Agencies can choose from more than 72 voices across multiple providers and select different models for different agents and use cases. Native GoHighLevel integration connects contacts, calendars, pipelines, opportunities, tags, custom fields, workflows, and sub-accounts without middleware or Zapier-style glue. Before answering, agents can pull caller history and CRM context to personalize conversations from the first ring.

Dograh
Dograh is an open source, self-hostable voice agent platform with a no-code workflow builder for creating production voice agents. Teams can choose their own inbound channels, speech-to-text, LLM, text-to-speech, and telephony providers, or replace the traditional cascade with speech-to-speech models for direct audio-in, audio-out conversations with natural turn-taking, interruption handling, and low latency. The platform supports inbound and outbound calling, widgets, telephony integrations, observability, traces, real-time analytics, hybrid pre-recorded voice plus TTS, and more than 70 languages. Its MCP server lets Claude Code, Cursor, OpenClaw, Codex, and other agent runtimes create, modify, and deploy voice agents directly from development environments. Dograh can run on your own servers, inside a private cloud or VPC, or in a managed environment, with support for models hosted entirely within your perimeter.

Gemini Audio
Gemini Audio is a set of advanced real-time audio models built on Gemini's architecture, designed to enable natural, fluid voice interaction and expressive audio generation through simple language prompts. It supports conversational experiences where users can speak, listen, and interact with AI in a seamless loop, combining understanding, reasoning, and response generation in audio form. It is capable of both analyzing and generating audio, allowing applications such as speech-to-text transcription, translation, speaker identification, emotion detection, and detailed audio content analysis. They are optimized for low-latency, real-time use cases, making them suitable for live assistants, voice agents, and interactive systems that require continuous, multi-turn dialogue. Gemini Audio also integrates advanced capabilities like function calling, enabling the model to trigger external tools and incorporate real-time data into responses.
