README
Eleven v4 API (ElevenLabs Text-to-Speech & Voice Generation)
Eleven v4 API converts written scripts into generated speech through ElevenLabs voice synthesis on Flaq AI. Developers and creators can select a voice, tune delivery stability, and adjust how closely the output follows the chosen voice. With character-based billing and an asynchronous task workflow, the text-to-speech API can be incorporated into narration tools, educational content pipelines, and applications that turn text into playable audio.
Key Features of Eleven v4 API
-
Script-to-Speech Generation: Convert supplied text into spoken audio for narration, product explainers, and other voiceover workflows.
-
Flexible Voice Selection: Choose an available preset voice name or supply an ElevenLabs voice ID accepted by the service to set the voice for a generation request.
-
Adjustable Delivery Stability: Tune the balance between a more varied delivery and a steadier reading through the stability control.
-
Voice Similarity Control: Adjust how closely the generated speech follows the selected voice, then review the result against your intended delivery.
-
Asynchronous Audio Generation: Submit a task, check its status, and retrieve the generated audio URLs after successful completion.
-
Character-Based Usage: Usage is based on the amount of text submitted, helping teams relate narration requirements to the scripts they plan to generate.
How to Use Eleven v4 API for Text-to-Speech on Flaq AI
-
Input: The text to be spoken, with an optional voice selection and delivery settings. Divide longer scripts into sections that fit the service's input limit.
-
Output: Generated speech audio available through URLs in the completed task result.
-
Voice Controls: Choose the voice and adjust stability and similarity to suit the script; listen to a sample before applying the settings across a larger project.
-
Task Workflow: Create the generation task, retain its task identifier, and check the result until it reaches a completed or failed state.
-
Capabilities: Text-to-speech generation with selectable voices and adjustable delivery, intended for spoken narration rather than music composition.
Best Use Cases for Eleven v4 API Integration
-
Video Voiceovers: Generate narration from an approved script for tutorials, explainers, and product videos.
-
Educational Audio: Turn lesson text and instructional passages into spoken material for learning content.
-
Article Narration: Create an audio reading of prepared written content, splitting longer material into manageable sections.
-
Application Voice Content: Produce spoken instructions and prepared messages that an application can retrieve and play.
-
Script Iteration: Regenerate revised passages and compare voice settings as a narration script develops.
-
Writing-to-Voice Workflows: Turn reviewed scripts from a text generation tool into spoken narration, connecting drafting and audio production in a single content pipeline.
Note Use text and voices you are authorized to use. Review pronunciation and delivery before publishing, and retrieve audio only after the task reports successful completion.
Eleven v4 vs Competitors: Comparative Analysis
-
Eleven v4 vs. Eleven v4 Turbo Both variants support the same script input, voice selection, stability, and similarity controls on Flaq AI. Eleven v4 Turbo offers a lower character-based rate for cost-effective narration and recurring voiceover production.
-
Eleven v4 vs. Amazon Polly Amazon Polly provides text-to-speech through AWS with multiple voice options. Eleven v4 offers an ElevenLabs voice workflow through Flaq AI with explicit stability and similarity controls; compare voice fit and integration requirements for your application.
-
Eleven v4 vs. Google Cloud Text-to-Speech Google Cloud Text-to-Speech converts text submitted through its API into playable speech. Eleven v4 provides voice generation through Flaq AI's task-and-result workflow, so the choice depends on your preferred voices and application integration.
