With a short reference recording, it can create a highly similar custom voice without model training; Qwen recommends 10–20 seconds of clear speech, while at least five seconds of continuous speech is required. The model supports real-time, streaming text-to-speech synthesis, allowing applications to accept text and return audio with low first-packet latency. It supports Chinese, English, French, German, Japanese, Korean, and Russian for cloned voices, with language hints available to improve identification during enrollment. Source recordings can use WAV, MP3, or M4A formats and should contain clean speech without background music, noise, or additional speakers.Starting Price: $0.26 per 10,000 characters -

Modulate Velma
Modulate
Velma is a voice-native AI model developed by Modulate as part of a broader voice intelligence platform, designed to understand conversations directly from audio rather than relying on text transcripts. Unlike traditional systems that convert speech into text and analyze it with language models, Velma uses an Ensemble Listening Model (ELM), a specialized architecture that processes multiple dimensions of voice simultaneously, including tone, emotion, pacing, intent, and behavioral signals. This allows it to capture the full meaning of a conversation, not just the words spoken, recognizing nuances such as stress, deception, sarcasm, or escalation in real time. It operates by combining hundreds of specialized detectors, each focused on specific aspects of speech like emotional state, inappropriate conduct, or synthetic voice indicators, and then fusing those signals into higher-level insights about what is happening in a conversation.Starting Price: $0.25 per hour -

Inworld TTS
Inworld
Inworld TTS is a state-of-the-art text-to-speech platform designed to deliver ultra-realistic, context-aware speech synthesis and precise voice-cloning capabilities at a radically accessible price. The flagship model, TTS-1, is optimized for real-time applications and supports low-latency streaming (first audio chunk in ≈200 ms) as well as multiple languages (including English, Spanish, French, Korean, Chinese, and more). Developers can use instant zero-shot voice cloning (5-15 seconds of audio) or professional fine-tuned cloning, add voice-tags for emotion, style, and non-verbal sounds, and switch languages while preserving voice identity. The larger TTS-1-Max model (in preview) offers even more expressive speech and multilingual strength. The platform supports both API and portal access, streaming or batch mode, and is designed for everything from interactive voice agents and gaming characters to branded audio experiences.Starting Price: $0.005 per minute -
