• Chatterbox TTS (Open Source, MIT Licensed) — The leading open-source TTS family, preferred over ElevenLabs in 63.75% of blind evaluations; available in three variants: original (emotion control + zero-shot cloning), Multilingual (23+ languages), and Turbo (fastest open-source inference + paralinguistic tagging for non-speech sounds); free forever with no API keys, no rate limits, and full on-premise deployment.
• Zero-Shot Voice Cloning from 5 Seconds — Clone any voice from a 5–20 second reference audio clip with no training, no fine-tuning, and no post-processing required; available via the cloud platform at $2/month/voice (Rapid) or $5/month/voice (Pro), or self-hosted via the open-source Chatterbox repo.
• Emotion Exaggeration Control — The only open-source TTS model with a single continuous emotion exaggeration parameter ranging from monotone to dramatically expressive; adjust intensity with a scalar value at inference time — no separate emotion prompts or post-processing required.
• PerTh Audio Watermarking — A Perceptual Threshold deep neural watermarker that embeds imperceptible, indestructible provenance data into every generated audio file using psychoacoustic masking; watermark encoding costs $0.0005/second and decoding costs $0.0002/second via the managed API.
• Resemble Detect — Multimodal Deepfake Detection — The highest-accuracy deepfake detection system available in 2026, achieving 96.7% accuracy across audio formats (WAV, FLAC, MP3, WEBM, M4A, OGG) and battle-tested against 160+ generative AI models; detects audio ($0.001/sec), video ($0.07/sec), and image ($0.04/sec) deepfakes with frame-by-frame analysis.
• AI Voice Agents — Deploy conversational voice AI agents via the managed cloud platform at $0.001/second, with full API access, team seat management ($20/month/user), and webhook integration for CRM and automation pipelines.
• AI Voice Changer and Speech-to-Text — Transform live or pre-recorded audio into target voices at $0.0005/second via the AI voice changer; transcribe audio to text with AI speech recognition at $0.001/second — both available on the Flex plan with never-expiring credits.
• Chrome Extension for Real-Time Deepfake Detection — A browser extension that applies Resemble Detect to audio and video content encountered while browsing, flagging deepfake media in real time before users interact with or share it — now available on the Flex plan at no additional subscription cost.
