7 Tips for Choosing an Automatic Translator
Choosing an automatic translator is less about impressive specifications and more about how reliably it handles real conversations. A traveler may need directions in a noisy station; a clinician may need clear communication with a patient. In both settings, a mistranslated number or instruction can matter. The right choice depends on language coverage, speech recognition, response time, offline access, and how the device handles recorded conversations. Small details count. Can it recognize accents? Does it work without a strong connection? Can users review or correct a phrase before sharing it?
There is a business case for taking language access seriously, too. CSA Research’s 2020 “Can’t Read, Won’t Buy” study surveyed 8,709 consumers across 29 countries. It reported that 76% preferred product information in their own language, while 40% said they would not buy from websites in other languages. These findings describe shopping preferences, not translator accuracy. That distinction matters. No headline statistic can confirm that a particular device will translate your terminology correctly. The seven tips ahead focus on practical checks: test the languages you actually need, compare translations with fluent speakers, and read the privacy terms before using sensitive conversations. Be skeptical of flawless claims. Even a capable translator can miss context, humor, or regional phrasing. A short trial with realistic sentences may reveal more than a polished product demo.
Prioritize languages: 76% prefer native-language product information (CSA, 2020)
When choosing an automatic translator, start with the languages your customers actually use. CSA Research reported in 2020 that 76% of consumers prefer product information in their native language. That preference can affect whether shoppers understand a size chart, compare materials, or follow care instructions. A long language list looks impressive, but reliable support for your priority languages matters more.
Test the translator with real product details, not only simple greetings. Try a fabric description, a measurement table, and a return instruction. Check whether units, tone, and key terms stay consistent across each example. Native speakers can spot awkward phrasing that automated checks may miss. Small differences matter. A polished screen can still hide a confusing translation, and I would not assume every language pair performs equally well. If customers speak regional varieties, test those too. Review results periodically as products and terminology change. One test is not enough.
Benchmark output with BLEU and COMET, metrics used in WMT evaluations
When comparing automatic translators, do not rely on a polished demo sentence. Build a small test set from your real work: support replies, product instructions, and short notices. Keep the source text and human reference translations unchanged across tools. Then score each output with BLEU and COMET, metrics used in WMT evaluations. BLEU compares matching word sequences; COMET uses learned models to estimate meaning and translation quality. Neither is a verdict.
For useful results, test several language directions and include numbers, names, and ambiguous phrases. BLEU may favor wording close to one reference, even when another natural translation differs. COMET can better reflect meaning, but its score is still an estimate, not proof of correctness. Review the outputs yourself, especially for customer-facing text. Record the metric version, test set, and settings so comparisons stay fair. I would not choose a translator from one high score; small samples can flatter performance. That is easy to miss. Check several low-scoring examples, too, and ask whether the errors matter in your workflow. A slightly imperfect benchmark can still help, if its limits are visible.
Check post-editing workflows against ISO 18587:2017
7 Tips for Choosing an Automatic Translator
Check post-editing workflows against ISO 18587:2017
A fluent demo is not proof of dependable translation. Ask how machine-generated text moves through human post-editing, from the first draft to final delivery. ISO 18587:2017 sets requirements for full human post-editing and outlines post-editor competencies. It does not certify a particular tool, so check the actual workflow.
Request a sample job record: the source text, machine output, edited version, and final quality checks. Look for clear instructions on audience, tone, and intended use. Ask who handles terminology, meaning errors, and unresolved ambiguities. A useful check. Can the provider explain why a sentence changed, not just show a polished result? Speed matters, but it can hide uneven editing. That gap matters.
CSA Research’s 2020 Can’t Read, Won’t Buy study surveyed 8,709 consumers across 29 countries. It found that 76% preferred product information in their own language, while 40% said they would not buy from websites in other languages. These figures make quality more than a stylistic concern. Test the workflow with real material, such as a product warning or a support article, and inspect edits line by line. Keep a record of recurring errors and review it with the provider. Even a well-documented process can miss context; I would not treat one successful sample as proof.

Check post-editing workflows against ISO 18587:2017
Use ISO 18587:2017 as a reference when evaluating full post-editing and post-editor competence. This practical checklist is not an official ISO scoring model. The bars count the checks listed for each stage.
Checklist: Screen the system for language-pair and domain fit, data handling, and integration; run a representative pilot and assess edit effort and output quality; confirm qualified post-editors, clear instructions, terminology consistency, and a feedback loop; check accuracy, language, and formatting; and define human sign-off and ongoing monitoring.
Protect submitted text with GDPR Article 5 data-minimization principles
An automatic translator may receive more than a sentence: names, addresses, invoice numbers, or hidden document details. GDPR Article 5(1)(c) says personal data should be adequate, relevant, and limited to what is necessary. Send less. Before choosing a tool, check whether it lets you translate selected text instead of an entire file, and whether you can remove identifying details first.
A practical test: replace a customer’s name with “Client A” and omit the account number. Translate only the paragraph needed, not the whole support thread. Check the provider’s retention settings, access controls, and whether submitted text may be used to improve services. These settings matter. I would still double-check them; privacy pages can be dense, and one missed toggle can change what happens to a submission.
The risk is not abstract. IBM’s 2024 Cost of a Data Breach Report put the global average breach cost at $4.88 million. Verizon’s 2024 Data Breach Investigations Report found that 68% of breaches involved a non-malicious human element. Those figures do not prove that translation tools cause breaches, but they underline the value of reducing exposure and reviewing workflows. Keep a short checklist beside the upload screen: remove identifiers, submit only necessary text, and confirm retention terms.
Assess market reach: 40% never buy from foreign-language websites (CSA, 2020)
Assess market reach before choosing an automatic translator. CSA Research reported that 40% of consumers would never buy from a website in another language (2020). That hesitation can cost more than a sale: shoppers may leave when product details, delivery terms, or return instructions feel unclear. A translated homepage is not enough. Check whether the tool handles product pages, checkout fields, and customer-support messages consistently. Small wording gaps matter.
Tip: Test real shopping journeys. Translate a product page, then inspect its size chart, shipping estimate, and return policy. Ask a fluent reader to review them. Pay close attention to currencies, dates, and short labels; automated systems can make these easy to misread. Keep a simple error log. It may reveal patterns you missed.
CSA Research also found that 76% of online consumers prefer product information in their own language. Use that finding to prioritize markets, but treat it as a starting point, not a forecast. Compare traffic, conversion, and support queries by language. A translator can widen access, though it cannot guarantee trust. I’d be cautious about relying on one quick test; local phrasing often needs another look.
