Anyone who’s tried translating a few Welsh phrases on Google Translate already knows the feeling: it’s quick, free, and often just right — until it isn’t. Since adding Welsh in 2016, Google Translate has become the go‑to for casual translation, but BBC Wales reported in 2021 that it sometimes produces what locals call “scummy Welsh”.

Estimated Welsh speakers globally: ~875,000 (ONS 2021) ·

Six key facts about the state of Welsh translation tools, one pattern: the gap between Google’s convenience and the grammatical nuance of the Welsh language is wider than many users expect.
| Fact | Value | Source |
|---|---|---|
| Official status of Welsh | De facto official language in Wales since 2011 | Welsh Government |
| Google Translate Welsh launch | 2016 | Locize |
| BBC “scummy Welsh” article date | November 2021 | BBC Wales |

| Google Translate overall launch | 2006 | Locize |

What is the most accurate Welsh translator?
Accuracy for Welsh is not a one‑size answer. Google Translate provides a baseline, but dedicated tools like Lingvanex may have higher precision for formal text, while dictionary‑based apps like Ap Geiriaduron excel at academic Welsh.
Lingvanex vs Google Translate for Welsh
A quick comparison of three leading tools shows distinct trade‑offs.
| Feature | Google Translate | Lingvanex | Bing Translator (Microsoft) |
|---|---|---|---|
| Price | Free | Freemium (subscription for full) | Free |
| Voice output | Yes (TTS) | Yes | Yes |
| Offline mode | No | Yes | No |
| Mutation handling | Inconsistent | Claims improved for formal Welsh | Similar to Google |
| Best for | Quick gist of informal phrases | Formal documents and grammar‑check | Web‑page translation |
The pattern: no free tool handles all four criteria well. Users in the SaySomethingIn forums say they check Google Translate only as a secondary source.
Google Translate trades grammatical precision for speed and volume. A 2021 UCLA study found it maintained meaning in 82.5% of translations across pairs, but Welsh — a low‑resource language — likely falls below that baseline (Phrase).
Criteria for judging translation accuracy
- Correct mutation after prepositions (e.g., “i” + soft mutation)
- Dialect consistency (North vs South Welsh vocabulary)
- Handling of compound verb‑noun constructions
- Voice output pronunciation quality

Can Google Translate speak Welsh?
Yes — Google Translate includes text‑to‑speech for Welsh on both mobile and desktop versions. The voice feature reads out translated phrases, which is useful for pronunciation practice, but the quality of the synthetic voice is a common point of criticism.
Voice output availability for Welsh
- Available on Android, iOS, and web via the speaker icon
- Reads translated text in a standardised Northern‑leaning accent
- Does not handle regional variations in pronunciation
Supported languages for speech on Google Translate
- Welsh is listed among the languages that support both text and voice translation
- For comparison, some low‑resource languages only have text‑only support
Voice can be a genuine learning aid, but if the underlying translation is grammatically wrong, hearing it read aloud simply reinforces errors. One Reddit user in r/learnwelsh noted they “would make errors on certain words” when relying solely on Google Translate’s voice output.
What is “I’m tired” in Welsh and other basic phrases?
Translating “I’m tired” correctly
The formal Welsh for “I’m tired” is “Rwy’n wedi blino”. However, colloquial variants include “Dw i wedi blino” (South) and “Fi wedi blino” (North). Google Translate typically outputs “Rwy’n wedi blino”, which is standard but may sound stiff in conversation.
Basic Welsh phrases for family terms
- “Dad” in Welsh: “Dad” (informal) or “Tad” (formal)
- “Mum”: “Mam” (most common)
- “I love you”: “Rwy’n dy garu di” (familiar) / “Rwy’n eich caru chi” (formal)
Google Translate often uses the formal variant for family terms, which can feel unnatural in casual speech. A forum user on SaySomethingIn advised using Google Translate sparingly for single words and “checking another source when in doubt” (SaySomethingIn).
Steps to verify your translation on Google Translate
- Type your English phrase into Google Translate.
- Click the speaker to hear the Welsh pronunciation.
- Paste the Welsh result into Bing Translator as a quick cross‑check.
- Look up each word in Ap Geiriaduron to confirm part of speech and mutation.
- If the phrase includes a preposition (e.g., “to”, “in”), verify the mutation manually using a grammar guide such as BBC Learn Welsh.

“Google didn’t translate correctly and would make errors on certain words, especially where mutations are involved.”
— Reddit user in r/learnwelsh
“Lingvanex claims to be the most accurate Welsh translator for formal text, citing improvements in grammar and mutation handling.”
— Lingvanex marketing materials
“The BBC report highlighted that Google Translate was producing what Welsh speakers called ‘scummy Welsh’ – grammatically broken translations that often change the meaning.”
— BBC News article (November 2021)
For anyone learning Welsh or needing a quick translation, Google Translate is a fast, free starting point — but it is not a finished product. The gap between its neural engine and the nuances of Welsh grammar, especially mutations and dialect, means that for anything beyond a single word, a dedicated tool like Lingvanex or a human translator is the safer bet. For the learner in Wales, the choice is clear: use Google Translate as a speed‑check, not a source of truth, or risk learning a phrase that sounds wrong to the people you’re trying to talk to.
