Description

Inworld AI provides enterprise-grade, real-time voice AI capabilities including text-to-speech (TTS), speech-to-text (STT), voice cloning, and LLM routing. Designed for consumer apps scaling to millions of users, Inworld offers controllable speech-to-speech that understands, reasons, and interacts naturally over WebSocket connections with sub-second response times.

Resemble AI is an enterprise generative AI security platform. It provides real-time deepfake detection for audio, video, and images, as well as multimedia watermarking, audio identity verification, secure voice cloning, and advanced text-to-speech. Built on proprietary models engineered for AI security, Resemble AI protects intellectual property and trains teams to prevent sophisticated vishing and social engineering attacks.

• Provides multi-lingual support spanning over 100 different languages with native-speaker quality.
• LLM Router passes third-party provider rates directly through with zero added markup.
• SOC 2 Type II certified and provides workflows compliant with GDPR and HIPAA.
• Integrates voice profiling to extract five paralinguistic metadata signals (emotion, style, accent, etc.) per audio chunk.
• Enables natural-language steering of voice parameters using bracketed markup instructions inside the text.
• Full OpenAI and Anthropic SDK compatibility through simple base URL configuration swaps.

• Enables high-accuracy voice cloning from as little as a 10-second audio sample.
• Integrates an automated bot to monitor and detect deepfakes in real time on Zoom, Teams, Meet, and Webex.
• Provides multi-platform deployment choices including cloud, on-premises, and air-gapped options.
• Features an open-source model option for high-quality text-to-speech.
• Verifies audio identity in real time with speaker validation from just 4 seconds of audio.
