What Acento (Accent) is for

Spanish is one language with an enormous amount of regional texture — a straw is "popote" in Mexico and "sorbete" in Argentina, "vos" replaces "tú" across a huge swath of Latin America, Argentines turn "ll" and "y" into a "sh" sound, and "coger" is a completely ordinary verb in Spain but one to avoid in Mexico. Acento (Accent) answers the question that comes up constantly for learners, travelers and anyone reading Spanish from more than one country: what's different here, and how different is it really — from one hand-curated, honestly-hedged reference.

What it does

The different everyday words used for one concept — a straw, a bus, a car, popcorn, a swimming pool, an avocado, and 25+ more — and which country or region uses each (vocabulary_variant); a region's tú/vos/usted pattern and vosotros-vs-ustedes plural (pronoun_usage_guide); general phonetic tendencies for a country — seseo vs. distinción, yeísmo, the Rioplatense žeísmo/sheísmo "ll"/"y" sound, aspiration of final /s/ (regional_accent_info); general formal/informal register tendencies by region (formality_guide); a free-text search across the whole dataset by word or by country/region (country_dialect_search); a false-friends glossary of words whose meaning or register genuinely changes between countries, flagged honestly but non-graphically (false_friend_glossary); a cross-country overlap lookup for a term, pointing to the sibling jerga (Mexico) connector for deeper Mexican slang (slang_overlap_note); general greeting norms by region — besos culture vs. handshake-more-common norms (greeting_guide); and a glossary of the linguistics terminology itself — voseo, seseo, yeísmo, registro and more (dialect_glossary).

What it is not

Not a corpus, a survey, or an academic dialectology database — Acento (Accent) is a hand-curated reference, and every phenomenon it describes (voseo, seseo, yeísmo and the like) is a well-documented, extensively studied linguistic pattern, but real usage is a spectrum. Within any single country, speech varies by region, city vs. countryside, class, generation and individual habit, and it shifts over time; nothing here is an absolute rule for how "everyone" in a country talks, and every claim is deliberately phrased as a commonly-described general tendency rather than a stereotype. It is not a slang dictionary either — for deeper Mexican Spanish colloquialisms, the sibling jerga (Mexico) connector is the dedicated reference.

Tools

Vocabulary & Search

vocabulary_variant — The different everyday words used for one concept across the Spanish-speaking world, and which country or region uses each -- e.g. a drinking straw is "popote" in Mexico, "pajilla"/"pitillo" in Colombia, "sorbete" in Argentina/Uruguay. Also matches on a specific variant word itself (searching "popote" finds the whole "straw" entry). Use for "what do they call a straw in Argentina", "words for bus across Latin America". Args: concept.

country_dialect_search — Free-text search across the whole dataset by word or by country/region: matches everyday-vocabulary concepts and variants, plus countries whose accent, pronoun, formality or greeting notes mention the query (e.g. searching "voseo" surfaces every voseo country). Use for "which countries use vos", "find everything about aspiration", "search for guagua". Args: query.

Grammar & Accent

pronoun_usage_guide — A region's second-person pronoun pattern: tú (tuteo) vs. vos (voseo) vs. usted for informal/formal singular "you", and vosotros (Spain) vs. ustedes (Latin America) for plural. Use for "is it vos or tú in Argentina", "do they use vosotros in Mexico", "when is usted used in Colombia". Args: region.

regional_accent_info — General, commonly-described phonetic tendencies for a country: seseo vs. distinción ('z'/soft-'c' vs. 's'), yeísmo and the Rioplatense žeísmo/sheísmo "ll"/"y" sound, aspiration or dropping of final /s/, and other notable pronunciation patterns. Use for "why do Argentines say 'll' like 'sh'", "do Cubans drop the s sound", "is there a lisp in Spain". Args: country.

Culture & Register

formality_guide — General tendencies in formal/informal register use for a region -- how readily "usted" is used with strangers, elders or peers, versus an informal default. Use for "is usted used a lot in Costa Rica", "how formal is Mexican Spanish with strangers". Args: region.

greeting_guide — General greeting norms for a region -- cheek-kiss (besos) culture vs. handshake-more-common norms, and similar everyday social tendencies. Use for "do people kiss hello in Spain", "is a handshake normal greeting in Peru". Args: region.

Watch-outs

false_friend_glossary — Words that mean something different -- or carry a different register -- in different Spanish-speaking countries (e.g. "coger" is neutral "to take" in Spain but vulgar slang in Mexico; "guagua" means "bus" in the Caribbean but "baby" in Chile/Peru/Bolivia/Ecuador). Flags each honestly, including where a word is vulgar in some countries and completely ordinary in others, described informatively rather than graphically. Use for "is 'coger' a bad word", "what does 'guagua' mean", "words that mean different things in different countries". Args: term.

slang_overlap_note — Cross-references a term with its equivalents (from the vocabulary-variant dataset) and/or its different meanings (from the false-friends dataset) across the Spanish-speaking world, and points to the sibling jerga (Mexico) connector for deeper Mexican-slang coverage beyond plain dialect variation. Use for "what else could 'concha' mean", "what's the overlap for 'guagua' across countries". Args: term.

Reference

dialect_glossary — Defines the linguistics terminology used throughout this connector: voseo, tuteo, seseo, distinción, ceceo, yeísmo, lleísmo, žeísmo/sheísmo, aspiración, americanismo, dialecto, registro. Use for "what's voseo", "what does seseo mean", "what's the difference between dialecto and registro". Args: term.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Acento (Accent) — Privacy Policy

Effective 24 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Acento (Accent) is. Acento (Accent) is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for a hand-curated reference to dialectal and vocabulary variation across the Spanish-speaking world: everyday-word variants by country, pronoun and accent patterns, formality and greeting norms, a false-friends glossary, and a linguistics glossary. You interact with your assistant; the assistant sends us only the arguments needed for that one lookup.

What we receive. The arguments of each tool call — a concept, a country or region, a search query, or a glossary term — the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Everything is answered from bundled, hand-curated reference files and nothing is stored. No request is forwarded to any third party — there is no upstream call at all, live or otherwise — and no query is logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant or your name, and we do not build a profile from your queries: each request is answered independently and nothing carries over between requests. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. None — the entire dataset is bundled with the server and answered locally. Hosting: Vercel (United States regions).

Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Acento (Accent) is a general-audience linguistics reference operated by the adult using the assistant; false-friend entries are flagged honestly (including where a word is vulgar in some countries) but described informatively rather than graphically, and the dataset never includes slurs or hate speech targeting a protected group.

Changes. We will post changes here with a new effective date.

Acento (Accent) — Terms of Service

Effective 24 September 2026. These terms govern use of the Acento (Accent) connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

1. The Service. Acento (Accent) returns a hand-curated reference to dialectal and vocabulary variation across the Spanish-speaking world — everyday-word variants by country, tú/vos/usted and phonetic tendencies (seseo, yeísmo and similar), formality and greeting norms, a false-friends glossary, and a linguistics glossary — from data hand-curated and verified at build time. It is accessed through an AI assistant or directly over MCP or HTTP.
2. A reference, not an academic dialectology corpus. Acento (Accent) is an independent linguistics reference tool, not affiliated with or endorsed by any linguistic institute, government body, or academy (including the Real Academia Española). Every phenomenon it describes is a well-documented general tendency in Hispanic dialectology, not an absolute rule for how every speaker in a country talks; real usage varies by region, generation and individual, and this Service should not be relied on as the final word on how any specific person or community speaks.
3. Honest, not sanitized — and never hateful. The false-friends glossary flags words whose meaning or register genuinely changes between countries, including where a word is vulgar in some countries and ordinary in others, described informatively rather than graphically. It does not include slurs or hate speech targeting a protected group, and should not be assumed to cover every term a user may encounter.
4. Acceptable use. Automated use within the published rate limits is welcome.
5. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
6. Data. Our Privacy Policy describes what we process. In short: your query is answered from bundled reference files, and nothing is stored.
7. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
8. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss arising from use of or reliance on the Service. Our total liability is limited to US $100.
9. Governing law. California law; venue in San Mateo County, California.
