In recent years, podcasting has surged in popularity becoming a dynamic platform for storytelling, education and entertainment. Text-to-Speech is driving podcast creation and publishing super-easy and fast. Audiobooks have been in the market, but older audiobooks used human voice artists or the author itself used to record voices for it, which was cumbersome and expensive. But, recent advancements in Text-to-Speech, which provides voice customization, ultra-realistic voices and the creation of audiobooks have become feasible with almost no cost of production. In this Article, we will understand what are the best text-to-speech tools/services which can be used for podcasts or audiobook creation and how to choose them according to individual needs.

Key Factors when choosing AI Text-to-Speech Tools

Voice Quality and Naturalness

Voice quality is paramount, especially for podcasts and audiobooks, which aim to replicate human speech and create a natural listening environment. Modern Text-to-Speech (TTS) systems, trained on vast datasets, effectively capture the nuances of human speech. Platforms such as play.ht and ElevenLabs provide real-time, human-like voices at competitive prices.

Customization & Control

Advanced TTS systems offer a wide range of customization options, including voice modulation, volume, pitch, tone, speed, and gender. For deeper control, users comfortable with code can utilize SSML (Speech Synthesis Markup Language) to fine-tune attributes like pitch, pronunciation, and volume.

SSML is an XML-based markup language that allows granular adjustments to TTS output. Learn more about SSML here.

Real-Time Capabilities

For those creating short videos, recording audiobooks, or summarizing audio content, real-time TTS is essential. Tools like TTSReader offer real-time transcription for PDFs, text files, or websites, along with a Chrome extension and human-like voiceovers. MicMonster provides a podcast-focused TTS tool with multilingual support and customization options for speed, pitch, and volume.

Multilingual Support

As global internet usage expands, multilingual content becomes essential. While early TTS systems were trained primarily on English, modern systems are trained on datasets from multiple languages and dialects, enhancing accessibility and personalization for podcasts and audiobooks.

Cost Structure and Usage Limits

Although real-time, human-like voices and multilingual support are invaluable for podcast and audiobook creation, cost remains a critical factor. Many platforms offer free tiers to test their TTS solutions, with paid subscriptions unlocking additional features. For more technically inclined users, custom TTS systems can be implemented locally.
