What developers ask before building on MiraEcho.
MiraEcho is a speech AI platform for developers. It provides text-to-speech (TTS), speech-to-text (ASR) and voice cloning through a single REST and WebSocket API, so you can add natural spoken audio and accurate transcription to any application.
The Flash tier delivers first-packet latency under 100 milliseconds. Audio starts streaming back almost as soon as you send text, which makes MiraEcho suitable for live agents, call automation and interactive apps where perceived wait time matters.
MiraEcho supports Japanese, English and Chinese today, with a large library of preset voices and additional languages expanding over time. Japanese synthesis is tuned for fluent, natural intonation and accurate pronunciation.
Yes. You can clone from a few minutes of reference audio, or design a new one from a text description. Clones work across synthesis just like the preset library, so your product can speak in a sound that is uniquely yours.
Both synthesis and recognition support streaming over WebSocket. TTS streams audio chunk by chunk as it is generated, and ASR transcribes microphone input in real time with timestamps and confidence scores — the building blocks for conversational agents.
Yes. You can sign up and start using cloning and synthesis for free, with no payment required upfront. It lets you evaluate quality and latency against your own workload before you scale.
