Should you use an AI voice clone or a human voice?

What can AI voices do well today?

A search for an AI voice clone usually leads to services such as ElevenLabs. In practice, AI voice means four different things:

AI voices are fast. You can change the text without booking a new session, turn one script into many languages and keep the same tone across hundreds of short pieces.

They also have weak spots. Emotion tends to go flat over long stretches, stress and rhythm can sound slightly off, names are often mispronounced, and listeners notice.

How good are AI voices in Latvian, and how do you test them?

Quality differs between tools and changes with every update, so test it yourself. Latvia has its own language-technology companies, Tilde among them, so include local options alongside the global names. Write one paragraph that contains all of the following, generate it, and listen on headphones together with a native speaker:

1. Personal and place names, both Latvian and foreign.
2. Numbers, dates and prices written as digits, and abbreviations such as SIA, LR and EUR.
3. Long vowels and soft consonants: ā, ē, ī, ū and ķ, ģ, ļ, ņ.
4. Word stress, which in Latvian usually falls on the first syllable.
5. A question and an exclamation.
6. A sentence that mixes languages, such as a Latvian sentence with an English brand name, or a Russian one with a Latvian street name.
7. A long sentence full of commas.

Generate the same paragraph in every tool you are considering, so you compare like with like. Listen for wrong stress, long vowels cut short, numbers read in the wrong grammatical case, a robotic rhythm at every comma and an accent that drifts as the paragraph goes on.

Latvian, with its long vowels, soft consonants and first-syllable stress, needs a more careful check than English. Run the same test for Russian and English too, with their own tricky names and numbers.

When does a human voice win?

Whether an AI voice is good enough depends on the job:

In advertising, the voice becomes part of the brand, and a stock voice from a library may already be speaking in other companies' videos.

Some audiences react badly when they find out that a voice they took for a person was generated. Say when a voice is synthetic, and decide case by case where an AI voice is acceptable.

Is it legal to clone someone's voice?

Start with consent. Get it from the speaker, in writing, and make it specific. It should say:

• which tool will be used;
• for which uses and channels;
• in which languages;
• for how long;
• whether the voice model may be reused;
• how consent can be withdrawn and the model deleted.

Settle these points before the first recording. They matter most when the voice belongs to an employee or a presenter who may later leave the company.

A recording that identifies a person is personal data under the GDPR. Treat voice samples and models that way: limit who has access, use them only for the agreed purpose and delete them when that purpose ends.

Read the tool's terms as well: who owns the voice model and the generated audio, and whether the provider may use your recordings.

EU rules, including the AI Act, require AI-generated or manipulated audio and video to be disclosed in some cases, and platforms increasingly ask creators to label synthetic content. Check the current requirements before you publish.

Never clone a public figure, a colleague or a client without their permission. None of this is legal advice; for contracts, ask a lawyer.

How do you record a clean voice sample for a licensed clone?

Start with the recording guide of the tool you will use, because the required length and format differ between tools and change over time. These rules hold for any of them:

1. Record in a quiet, soft room with no echo.
2. Use one good microphone at a constant distance.
3. Read natural, varied text in the target language, in the tone you want the clone to have.
4. Leave out music, effects and heavy noise reduction.
5. Save a mono WAV file at 48 kHz / 24-bit, unless the tool asks for something else.
6. Record a separate sample for each language you need.
7. Archive the raw files together with the signed consent.

A studio session gives you a clean, consistent sample on a professional microphone. At Baltic Podcast Studio in Riga you can record a human voice-over for €60/h; ask for the unedited file as well as the mastered one. The cloning itself happens in the tool you choose.

What does a hybrid workflow look like?

One way to combine the two:

1. Record the pieces that carry the brand with a human voice: the advert, the intro, the main video.
2. Archive the clean recordings together with the consent.
3. If you use a licensed clone or a stock AI voice for updates and smaller pieces, keep their scripts in the same style as the rest.
4. Have a native speaker review every AI output before it is published.
5. Label the AI voice where the rules require it or where your audience expects it.
6. When a piece becomes important, re-record it with the human voice.

Content in Riga is often made in Latvian, Russian and English, and AI dubbing can produce first drafts of the other versions. Have a native speaker check the pronunciation and tone of each one before it goes out; translating and dubbing a video covers that workflow in detail.
