Murf API

What it does

Murf API is a set of developer APIs that turn text into speech and live audio into text. Text-to-speech takes a script and returns audio from a library of 150+ voices across 35 languages, with control over pitch, speed, prosody, and audio duration. Speech-to-text (Beta) takes live audio and returns transcription in 12 languages. Dubbing and voice changer endpoints convert existing audio or video, and a translation API translates text before speech generation.

Developers use the APIs to add speech generation and transcription to applications, or to prepare voiceovers and localized audio. Falcon is intended for real-time streaming conversations, while Gen2 addresses expressive non-streaming synthesis. Custom pronunciation helps with brand names and specialist vocabulary. The application must provide its own conversation logic and any external model or telephony connections.

Murf API suits developers building voice applications and teams automating audio production. Create an account, obtain an API key and follow the REST or Python examples for the chosen endpoint. Rates and language coverage differ by service. Gen2 streaming has been decommissioned, while its non-streaming endpoints remain available; speech-to-text is labeled Beta. Check the endpoint-specific limits and commercial terms before production use.

What it can do

• Generate speech from text with configurable voices and pronunciation
• Stream speech through Falcon for conversational applications
• Use Gen2 for non-streaming expressive speech synthesis
• Dub existing audio or video through the appropriate endpoint
• Transform recordings with the voice-changer endpoint
• Transcribe live audio with the Beta speech-to-text service

Example workflows

Speak an application response

Illustrative example. Supply response text from your application, send it to a Falcon streaming endpoint and play the returned audio. Handle the surrounding conversation and telephony connection in your application.

Localized voiceover

Illustrative example. Input: English script and target language. Steps: call the translation API, then generate speech with a library voice in the target language. Output: audio file in the target language.

Get started

Homepage offers a free API key and documentation.

1. Create an account and obtain an API key from the Get Free API Key link.
2. Read the Quickstart in the API documentation and make a first text-to-speech call.
3. Install the Python SDK from GitHub or call the REST endpoints directly.

The API page advertises Falcon at $0.01 per generated minute. Confirm current model applicability, free allowance, minimums and rates for Gen2, transcription and dubbing in the API table. Studio subscription rates do not apply.
