Speechify is an AI voice and text-to-speech platform that reads written material aloud and also provides speech-to-text, conversational, and business-focused AI tools. Its SpeechifyAI service offers text-to-speech and realtime voice-agent APIs through a single interface, with streaming synthesis, zero-shot voice cloning from a consented reference clip, SSML-based emotion control, and multilingual output for English, German, Mexican Spanish, French, Italian, and Brazilian Portuguese. The service includes the Simba model family, which the site describes as streaming-native speech models designed to model voice identity, expression, and language for realtime conversation. Speechify was co-founded by Cliff Weitzman, who initially built it to consume written material through audio.

Moonshine Voice is an open-source AI toolkit for developers building real-time voice agents and applications. It provides on-device speech-to-text, intent recognition, and text-to-speech, including streaming transcription that processes audio while the user is still speaking. The project offers speech-to-text models ranging from higher-accuracy models to approximately 1 MB models and provides one library for Python, JavaScript/WASM, iOS, Android, macOS, Linux, Windows, and Raspberry Pi. It is used by Gemma Translator for speech recognition and speech output, and can run without an account or API keys. The project is distributed under the MIT License, including its models by default, with legacy non-streaming models for non-English languages covered by a non-commercial Moonshine Community License.

Speechify Work is Speechify’s work-focused AI assistant. It is described as helping users read, dictate, and work with information, with a role comparable to a general-purpose assistant such as Jarvis.

Smallest AI is a voice-AI platform offering text-to-speech, speech-to-text, speech-to-speech, and orchestrated voice-agent models for real-time deployments.

Hydra is a speech-to-speech AI model from Smallest AI for asynchronous speech input and output, with support for text and tool calls.
