Why technical terms break ordinary dictation
Speech-to-text models are trained mostly on everyday speech, so they default to common words. When a doctor says "metoprolol", a generic model hears something rare and guesses something common — "met a pro lol". Same failure for legal Latin ("res judicata"), software tools ("Kubernetes", "PostgreSQL"), and finance vocabulary ("EBITDA"). The fix isn't a better microphone; it's telling the transcription what vocabulary to expect.
How term packs work
Enable a pack in the Dictionary tab (or pick your field at signup) and Pithflow biases every transcription toward that vocabulary BEFORE the audio is decoded — the model expects the terms, so it recognizes them. A second pass repairs near-misses: if a mangled rendering slips through, the AI cleanup compares it against the pack and restores the correct form. Your personal dictionary terms always take priority on top.
The packs — 9 fields, English + Español, ~3,100 curated terms
Every specialty comes in both languages — toggle English and Español separately from the pack's card in the Dictionary tab.
• Medical — top-prescribed drugs, clinical exam vocabulary, diagnoses, anatomy, procedures; en español, vocabulario clínico y fármacos with Mexican and LATAM usage.
• Legal — Latin phrases, litigation and contract vocabulary; en español, amparo, derecho procesal, civil y notarial mexicano.
• Software & engineering — tools, frameworks, infrastructure, CS concepts; en español, from despliegue continuo to aprendizaje automático.
• Finance & accounting — reporting terms, instruments, filings, acronyms; en español, CFDI, SAT, RESICO and the rest of Mexican tax vocabulary.
• Science & research — lab techniques, genetics, statistics, publishing vocabulary, in both languages.
• Mental health & therapy — modalities, diagnoses, clinical documentation, in both languages.
• Education & teaching — IEP/504 documentation, pedagogy, literacy, assessment; en español, planeación didáctica, USAER, evaluación formativa.
• Construction & trades — framing, concrete, MEP, permits and project paperwork; en español, cimbra, varilla, tablaroca, instalación hidrosanitaria.
• Marketing & sales — SEO/PPC metrics, funnels, attribution, platform names, in both languages.
Bilingual professional dictation
Spanish-speaking professionals can enable the English and Spanish packs for their field — any field — and code-switch freely: "revisión sobre hipertensión, citing the metoprolol trials" transcribes each part correctly. Auto-detect handles the language per dictation; the packs handle the vocabulary in both.
Teach it your own terms
Packs cover the high-yield vocabulary of each field, not every regional brand name or niche term. For the rest: the personal Dictionary (add a term once, it's recognized from then on) and Fix a word in the History list on Home — spot a miss, type the correction, one click. Both feed the same recognition biasing as the packs.
A note for healthcare users
Term packs improve transcription quality; they don't change data handling. Pithflow is not HIPAA-eligible and does not sign BAAs, so do not dictate protected health information with it. The medical packs are for the medical writing that carries no patient data: research, teaching, and administration.
