OpenAI FM

Description

OpenAI FM is an interactive demo by OpenAI that showcases their new text-to-speech (TTS) models, allowing users to convert input text into expressive, human-like speech in real time.

OpenAI FM acts as a playground for developers and creators to experiment with OpenAI’s latest TTS capabilities, including gpt-4o-mini-tts and other voice models. Users can paste text, select from various voice styles (Alloy, Ash, Ballad, etc.), and apply “vibe” or emotional tone controls to shape how the speech sounds. The demo is built using Next.js and connects to OpenAI’s Speech API to generate the audio.

Key Applications

Long-Form Content Generation: Drafts comprehensive articles, blog posts, reports, and scripts using AI, significantly reducing initial writing time.
Marketing Copy & Campaigns: Creates high-converting copy for emails, social media ads, landing pages, and product descriptions across multiple channels.
Brand Voice Consistency: Learns and replicates a company's unique tone and style guidelines to ensure all generated content is on-brand.
Specific Workflow: A content manager uses a blog post template, inputs key points, and Jasper generates a full 1,500-word draft, which is then refined by a human editor.

Who It’s For

This platform is built for marketing teams, content agencies, and businesses that need to scale their content production efficiently. It solves the problem of writer's block, slow content velocity, and maintaining a consistent brand voice across a large volume of outputs. The primary buyer persona is a Content Director or Marketing Manager at a scaling company who oversees a content calendar and a team of writers.
