Introducing ElevenLabs Flash V2 on WaveSpeedAI: Ultra-Low Latency Text-to-Speech for Real-Time Applications

The demand for natural, responsive AI-generated speech has never been higher. Whether you’re building conversational AI agents, developing interactive applications, or creating content at scale, the ability to convert text to lifelike audio in milliseconds can make the difference between a seamless user experience and a frustrating one. Today, we’re excited to announce the availability of ElevenLabs Flash V2 on WaveSpeedAI—bringing you ultra-low latency text-to-speech with exceptional quality, all through our streamlined inference platform.

What is ElevenLabs Flash V2?

ElevenLabs Flash V2 represents a significant leap forward in text-to-speech technology. Designed specifically for scenarios where speed is critical, Flash V2 generates natural-sounding speech in just 75 milliseconds plus network latency. This makes it one of the fastest TTS models available today while maintaining the audio quality that has made ElevenLabs a leader in the synthetic voice space.

In blind tests conducted by human evaluators, ElevenLabs Flash consistently outperformed comparable ultra-low-latency models, earning recognition as the fastest model with quality of its kind. The model delivers crisp pronunciation, smooth pacing, and expressive tone that brings written content to life with remarkable authenticity.

Key Features

Flash V2 comes packed with capabilities that set it apart from other TTS solutions:

• Ultra-Low Latency: Generate speech in approximately 75ms, making it ideal for real-time conversational applications where every millisecond counts
• Natural Prosody: Clear, humanlike articulation with proper intonation and pacing that sounds genuinely natural
• Extensive Voice Library: Access a rich collection of multi-lingual voices with distinct personalities and characteristics
• Fine-Grained Control: Adjust similarity (0-1) to control how closely the output matches the base voice timbre, and stability (0-1) to manage consistency in delivery
• Speaker Boost: A specialized feature that improves the reading of English numbers, units, dates, and measurements—essential for financial, technical, and instructional content
• Strong English Performance: Optimized for clear reading of numerals, dates, and complex text patterns

Voice Customization Options

Flash V2 provides intuitive controls that let you fine-tune your audio output:

• Similarity Slider: Higher values produce output that more closely matches the original voice timbre
• Stability Slider: Increase for more consistent delivery across longer texts, or decrease for more dynamic variation
• Speaker Boost: Toggle on for improved handling of numbers, units, and measurements in English

Real-World Use Cases

The combination of speed and quality makes Flash V2 suitable for a wide range of applications:

Conversational AI and Voice Agents

For customer service bots, phone-based agents, and interactive voice response systems, Flash V2’s ultra-low latency ensures natural conversation flow. Users experience minimal delay between their input and the AI’s spoken response, creating interactions that feel genuinely conversational rather than robotic.

Interactive Applications and Gaming

Game developers and application builders can integrate dynamic, responsive voice interactions without the jarring pauses that break immersion. Character dialogue, tutorials, and in-game narration all benefit from the speed and expressiveness Flash V2 provides.

Content Creation at Scale

Creators producing voiceovers for videos, podcasts, tutorials, and digital content can leverage Flash V2 for rapid iteration. The fast generation time means you can experiment with different voices and phrasings without lengthy wait times, accelerating your creative workflow.
