AI voiceover for B2B video: 5 text to speech tools (2026)

Some links in this article are affiliate links. If you choose a tool through one of them, we may earn a commission. It costs you nothing extra and does not change our assessment.

An AI voiceover is spoken audio made by software instead of a voice actor.

You type a script and pick a voice. Minutes later, you have an audio file.

The verdict: an AI voice is good enough for demos, tutorials and ads. For a brand film, a human voice still wins. What tips the scale comes down to three things: accent, licence and pronunciation.

Below, we compare five text to speech tools: ElevenLabs, Microsoft Azure AI Speech, Google Cloud Text-to-Speech, Murf and HeyGen.

How we checked: prices and language support come from the vendors’ own pages, checked on 21 October 2026. We use a partner link for ElevenLabs. The order follows the use case, not that link.

What exactly is an AI voiceover?

An AI voiceover is text to speech from a neural voice model that mimics intonation, pauses and stress.

Older systems sounded like a sat nav. Newer models put the stress where a person would.

There are three flavours:

• Stock voice: you pick a ready-made voice from a library
• Voice clone: the tool imitates a real voice from recordings
• AI dubbing: the tool translates an existing video and voices it in another language

It’s a form of generative AI, just like text or image generators.

So the same questions about quality, rights and transparency apply as with AI content marketing.

When should you use an AI voice, and when a human voice?

Pick an AI voice when speed and flexibility matter more than emotion.

A product demo changes with every release. You can regenerate an AI voice with one edited sentence, without booking a studio.

A brand film has to move people. That’s where an experienced voice actor’s timing makes the difference.

This diagram helps you choose:

By video type, the choice looks like this:

Rule of thumb: if the script changes often, go AI. If the video has to move people, go human.

What should you check in an AI voice for the Belgian market?

Check the accent first, then the licence, then the pronunciation.

Those three decide whether your video sounds credible in Flanders and Wallonia.

Flemish or Netherlands Dutch accent

A Netherlands Dutch voice in a Flemish ad quickly sounds like a Dutch web shop.

Not every tool offers a Belgian variant. Google and Azure label their voices with a language code, such as nl-BE for Dutch from Belgium.

French works the same way with fr-BE. The choice there is smaller.

Licence for commercial use

A free plan often isn’t meant for ads or client videos.

At ElevenLabs, the commercial licence only shows up on the paid Starter plan. So always read the terms of the plan you’re actually on.

Pronunciation control

Your brand name, product names and English jargon are what goes wrong most often.

A good tool lets you steer pronunciation, with phonetic spelling or SSML: a markup language that tells the engine how a word should sound.

Which AI voiceover tools are strongest for B2B?

Every tool below gets the same four questions: who it’s for, what it costs, how it handles Dutch and French, and where the catch is.

1. ElevenLabs

Best for: marketers who want an expressive voice for demos, ads and podcasts.

Price: free with 10,000 credits a month, roughly 10 minutes of text to speech, but without a commercial licence. Starter costs $6 a month, Pro $99 a month (pricing page, checked October 2026, excluding taxes).

Dutch and French: both are on the list of 90+ languages. A Flemish or Belgian French accent isn’t mentioned on the languages page.

Watch out: the commercial licence only starts at Starter. A free account won’t cover an ad.

We work out what those credits mean in minutes of voiceover in our guide to ElevenLabs pricing.

ElevenLabs is best known for the natural intonation of its voices.

That makes it strong for content where a voice has to persuade, like a video ad or a podcast intro.

Need a Flemish accent? Test a few library voices with your test sentence.

Rule of thumb: pick ElevenLabs when the sound matters more than an official nl-BE label.

2. Microsoft Azure AI Speech

Best for: teams with a developer who want fixed Belgian voices through an API.

Price: the free F0 tier gives you 0.5 million characters a month for neural voices. The paid rates weren’t readable on the page: price on the vendor site (checked October 2026).

Dutch and French: two nl-BE voices (Dena and Arnaud) and two fr-BE voices (Charline and Gerard), according to Microsoft’s language support page.

Watch out: Azure is a cloud platform, not an editor for marketers. Without someone who works with APIs or SSML, you won’t get far.

The big upside? Azure has genuine Belgian voices in both national languages.

For a brand rolling out the same demo in Flanders and Wallonia, that’s rare.

3. Google Cloud Text-to-Speech

Best for: high volumes, like hundreds of short product videos or a knowledge base with audio.

Price: Chirp 3: HD voices cost $30 per million characters after a free usage limit of 1 million characters. Standard and WaveNet voices cost $4 per million characters after 4 million free characters (pricing page, checked October 2026).

Dutch and French: 34 nl-BE voices, 30 of them Chirp 3: HD. For French there are voices for France and Canada, but no fr-BE.

Watch out: as with Azure, you work through an API or console. For French-speaking Belgian videos, you’ll use a voice from France.

So Google has the widest range of Flemish voices on this list.

Rule of thumb: pick Google for Dutch volumes, Azure if you need fr-BE as well.

4. Murf

Best for: marketers who want a studio editor, no code.

Price: the API costs $0.01 per 1,000 characters (Falcon) or $0.03 per 1,000 characters (Gen2), with $10 of free credit. For the Studio plans: price on the vendor site (checked October 2026).

Dutch and French: the Dutch page mentions Belgian Dutch (Flemish) voices for campaigns in Belgium, but the voice list doesn’t say which ones. French comes from France and Canada.

Watch out: Murf says all audio from paid plans is cleared for commercial use. On a free account, you can’t download anything.

Murf is built for people who edit videos in an editor.

You lay out text, voice and visuals on a timeline. That suits an explainer video or webinar intro.

5. HeyGen (AI dubbing)

Best for: translating an existing video, like a webinar or interview, into another language.

Price: free for 3 videos a month with a watermark, up to 1 minute each. Creator costs $29 a month, Pro $49 and Business $149 plus $20 per extra seat (pricing page, checked October 2026).

Dutch and French: the help centre lists Dutch (Belgium, Netherlands) and French (Belgium, Canada, France, Switzerland) for video translation.

Watch out: HeyGen keeps the original speaker’s voice and lip movements. That’s a voice clone, so ask for consent first.

HeyGen isn’t a classic voiceover tool.

It shines when you want to offer your Dutch-language B2B webinar lead engine in French too.

Which tool should you pick for which video?

Start with the video you need to make right now. Here’s the fastest route:

For LinkedIn ads, you’ll often make three or four variants.

Then quick regeneration pays off.

Rule of thumb: choose for your next video, not for the longest feature list.

What does the AI Act say about AI voices and deepfakes?

Article 50 of the AI Act requires transparency about synthetic audio.

According to the text on the European Commission’s AI Act Service Desk, two duties apply:

• Providers of the AI tool mark synthetic audio in a machine-readable way
• Deployers who publish a deepfake disclose that the audio was generated or manipulated by AI

A deepfake, under Article 3, is AI-generated audio, image or video that resembles existing people and would falsely appear authentic.

Cloning your CEO’s voice? That’s quickly a deepfake.

The regulation applies from 2 August 2026. Systems already on the market before that date have until 2 December 2026 to meet the marking duty in Article 50(2).

For clearly creative or satirical works, the disclosure duty is lighter, but it doesn’t disappear.

In doubt? Ask your legal adviser. For working responsibly, read our guide to ethical AI content.

Rule of thumb: a real person imitated means consent and a disclosure, every time.

How do you make an AI voiceover for a 60-second product demo?

Work in six steps, from script to subtitles.

Say a SaaS company from Ghent is showing a new reporting feature in a one-minute demo, in Dutch and French.

Step 1: write the script for the ear

Write short sentences you can say out loud. A spoken script isn’t web copy.

Read it aloud with a stopwatch and cut until it fits into 60 seconds.

Step 2: fix the pronunciation of brand names

Put your brand name and product names in your test sentence. If a name sounds wrong, spell it phonetically or use SSML.

Check English jargon like “dashboard” or “workflow” separately in the Dutch and French versions.

Step 3: choose the voice and generate line by line

Pick a voice that matches your tone of voice.

Generate per sentence or per paragraph. That way you can edit one line later without redoing everything.

Step 4: export and mix

Export in a lossless format like WAV if you’re still adding music.

Keep the music low under the voice. Every word should stay clear.

Step 5: add subtitles

Subtitles help viewers who watch with the sound off, for example in their LinkedIn feed.

Use your script as the base for the subtitle file. That way the names are right from the start.

Subtitles and a transcript also help your video SEO.

Step 6: disclose AI and keep your records

Disclose the AI voice in the description.

Keep the script, the tool you used and your plan. Then you can show later that you had a commercial licence.

Frequently asked questions

Is AI voiceover free?

For testing, yes. ElevenLabs, Azure, Google and HeyGen all have a free tier or free usage limit. For ads and client videos, you’ll usually need a paid plan with a commercial licence.

Is there text to speech with a Flemish accent?

Yes. Google Cloud has 34 nl-BE voices and Azure has two. Murf mentions Flemish voices. ElevenLabs doesn’t list a Flemish accent on its languages page (all checked October 2026).

Can I use an AI voice in an ad?

Yes, if your plan allows commercial use. At ElevenLabs that’s from Starter, at Murf on paid plans. Read the terms of your own plan.

Do I have to disclose that a voice is AI-generated?

For a deepfake, like a cloned voice of a real person, yes: that’s what Article 50 of the AI Act asks. For a stock voice, a short note in the description is a good habit.

What’s the difference between text to speech and AI dubbing?

Text to speech turns a script into audio. AI dubbing translates an existing video and voices it in another language, often in the original speaker’s voice.

Can I use an AI voiceover for a podcast?

For an intro, outro or jingle, sure. A full podcast runs on real conversations. Find out why in our guide to podcast guesting for B2B authority.

What’s your next step?

Pick your next video. Test three voices with the same test sentence. The accent will pick your tool.
