Make your Substack posts and newsletter listenable.

This guide explains how to convert your Substack posts into audio using BeyondWords' Text-to-Speech Editor, and how to insert the audio mp3 into your post via the Substack web player.

Alternatively, you can insert your BeyondWords audio via a shareable audio URL or Spotify podcast embed.

Are there any other ways to insert audio?

We recommend using the mp3 upload method outlined above, but you can also insert BeyondWords audio into Substack posts via link or Spotify embed. Other forms of audio embeds (for example, iFrame embed) are not possible in Substack at the moment. You cannot attach files to Substack posts or emails, either.

  • Link: Draft a post in Substack, create the audio version with BeyondWords' Text-to-Speech Editor, then copy and paste the shareable audio URL into your draft post. You might want to use anchor text like ‘Listen to the audio version here’.

  • Spotify embed: Draft a post in Substack, create the audio version in BeyondWords with Spotify distribution, then copy and paste the Spotify podcast URL directly into your draft post. A player embed will be generated automatically, allowing users to read and listen to the post in one place.

Will subscribers be able to play audio in their emails?

The Substack web player and Spotify embed player will be previewed in emails, but they will not be playable. Subscribers will need to click through to the web version of the post in order to listen.

If you link to the shareable audio URL, the user will be taken to a separate webpage with the BeyondWords Large Player, which is customizable.

Can I make audio-enabled posts available to subscribers only?

Yes, you can make audio-enabled posts available to subscribers only. Simply draft your post, select ‘Publish’, then select ‘Only paid subscribers’ before ‘Send to everyone now’. You may need to turn on paid subscriptions first.

Can I use audio in different sections of my publication?

Yes, you can use audio in different sections of your Substack publication. This makes it possible to offer separate subscriptions for various types of post — for example, you could publish your posts and audio in different languages.

If you want the option to use the mp3 upload method in your new section, you will need to create a ‘Podcast’ section rather than a ‘Newsletter’ section. (You can still publish text-only posts in Podcast sections.)

Otherwise, you can simply create a new ‘Newsletter’ section and insert audio using the link or Spotify embed method.

Should I use the podcast feed URL in BeyondWords or Substack?

Both BeyondWords and Substack allow you to distribute your audio content via podcast feed. This makes it possible to publish on platforms like Spotify, Apple Podcasts, and Google Podcasts.

If you use the Substack podcast feed URL, all audio content published via the Substack web player will be distributed (this includes uploaded mp3s and audio recorded directly in the Substack editor). If you wish to delete any published podcast, you will need to delete the audio from the associated post.

If you use the BeyondWords podcast feed URL, all audio content created on your BeyondWords project will be distributed.

How to create a podcast feed with BeyondWords

Should I import my BeyondWords podcast feed to Substack?

If you import your BeyondWords podcast feed to Substack, your existing podcasts will be cloned and published as audio-enabled posts (episodes) in Substack. You can then edit these episodes.

Your BeyondWords podcasts will not be deleted, and future podcasts will not be automatically imported. You can continue using your BeyondWords podcast feed like normal.

Importing your BeyondWords podcast feed URL is therefore recommended if you wish to mass-import existing podcasts to Substack.
