When Podcasts Become Audiobooks: The Lines Between Audio Formats Are Disappearing

The worlds of podcasting and audiobooks have always shared plenty of common ground, but the line separating the two formats is becoming increasingly difficult to see. A new Forbes piece explores how podcasting and audiobooks are converging, creating a rapidly evolving audio landscape where the same listeners, platforms, creators, and technologies are increasingly serving both markets.

The overlap is already significant. Roughly half of Americans have listened to both a podcast and an audiobook, while about 55 percent of audiobook listeners also listen to podcasts. Those numbers point to something bigger than simple audience crossover. They suggest that consumers are becoming increasingly comfortable moving between different forms of spoken word audio, depending on what they want to hear and how much time they have.

Podcasts and Audiobooks Are Moving Closer Together

Traditionally, podcasts and audiobooks occupied fairly distinct spaces. Podcasts were generally associated with ongoing shows, interviews, news, entertainment, and conversational content, while audiobooks were tied to professionally produced versions of published books.

That distinction is becoming less relevant.

Many podcasts now use long form storytelling, scripted narration, sound design, music, and serialized storytelling techniques that would feel perfectly at home in an audiobook. At the same time, audiobook publishers and platforms are experimenting with episodic releases, original productions, celebrity narration, conversational formats, and other approaches that increasingly resemble podcasting.

In some cases, a serialized podcast can essentially function like an audiobook released one chapter at a time.

For listeners, that distinction may not matter at all. They are simply looking for compelling audio content.

Audible and Spotify Want Both Audiences

The convergence between podcasting and audiobooks also has major implications for the companies competing for listeners.

Audible has long dominated the audiobook space, but its ambitions extend well beyond traditional audiobooks. Spotify, meanwhile, has established itself as one of the biggest podcast platforms while making a significant push into audiobooks.

That creates an interesting strategic battle.

Rather than forcing consumers to choose between podcasts and audiobooks, the major platforms increasingly want to become the destination for all spoken word audio. The goal is straightforward, keep the listener inside the same ecosystem for as much of the day as possible.

A listener might discover a podcast in the morning, switch to an audiobook during a commute, listen to another podcast while exercising, and return to an audiobook in the evening. From the platform's perspective, these are not necessarily separate markets. They are different forms of audio consumption competing for the same listener's attention.

The Rise of the Podcast That Sounds Like an Audiobook

Perhaps the most interesting part of this convergence is happening at the creator level.

Podcasting has evolved dramatically from its early reputation as relatively simple, conversational audio. Today, highly produced podcasts can feature professional narration, multiple voices, original music, sound effects, cinematic sound design, archival material, and carefully structured storytelling.

True crime podcasts are an obvious example.

A well produced serialized true crime podcast can have many of the characteristics of an audiobook, including a narrator, chapters or episodes, a carefully constructed narrative, character development, interviews, research, and extensive sound design. The primary difference may simply be how the content is distributed.

This opens up interesting opportunities for publishers, authors, podcast producers, and audio production companies.

A book can potentially become an audiobook, a podcast series, or even both. A podcast can potentially develop into a book, while an existing book can become the foundation for an episodic audio production.

The boundaries are becoming increasingly fluid.

AI Is Accelerating the Convergence

Artificial intelligence is another major factor pushing podcasting and audiobook production closer together.

AI narration, voice modeling, transcription, translation, editing, noise reduction, and other audio production technologies are making it easier and faster to create spoken word content. What once required substantial studio time, production resources, and specialized expertise can increasingly be accomplished with the assistance of AI tools.

That does not necessarily mean human narrators and producers are disappearing. In fact, the opposite may be true for premium productions. Human performance, interpretation, pacing, emotional nuance, character development, and creative direction remain extremely important when the goal is to create compelling audio.

But AI can lower production barriers.

For independent creators, publishers, authors, and businesses, that could mean more experimentation with formats that sit somewhere between podcasts and audiobooks.

What This Means for Podcast Producers and Audiobook Creators

The convergence of podcasting and audiobooks represents an opportunity for creators who understand both sides of the audio industry.

A podcast producer who understands audiobook production can bring techniques such as detailed narration editing, mastering, pacing, consistency, and professional voice production into podcast projects.

Likewise, audiobook producers can draw from podcasting's strengths, including serialized storytelling, conversational formats, sound design, audience engagement, and ongoing content strategies.

The result could be a new generation of audio productions that do not fit neatly into either category.

Instead of asking whether something is a podcast or an audiobook, perhaps the more useful question will be, what is the best audio format for this story and this audience?

The Future of Spoken Word Audio

The growing relationship between podcasting and audiobooks reflects a much larger shift in how people consume spoken word content.

Listeners increasingly care less about the traditional label attached to a piece of audio and more about whether it is interesting, convenient, immersive, and worth their time. Streaming platforms are responding by bringing more forms of audio together, while creators are experimenting with formats that blur the boundaries between them.

AI will likely accelerate that process even further.

For podcast producers, audiobook publishers, authors, narrators, and audio production studios, this convergence creates both challenges and opportunities. The competition for listener attention will become more intense, but the number of ways to tell a story through audio will continue to expand.

The future of podcasting and audiobooks may not be about choosing one format over the other. It may be about recognizing that they are becoming two parts of the same much larger audio ecosystem.

And if that happens, the question may no longer be whether podcasts are becoming more like audiobooks.

It may be whether we still need to distinguish between them at all.
