Theoretical and methodological issues regarding the use of language technologies for patients with limited English proficiency

Paper · 2007 · Harold Somers

Summary

This position paper asks how language technology can help healthcare providers and patients who share no common language, using patients with limited English proficiency (LEP) as the case. Somers maps the whole pathway to healthcare: self-diagnosis online, booking appointments, history-taking, consultation, pharmacy, and follow-up care. He shows that each step calls for a different technology, such as SLT, controlled-language MT, text simplification or computer-based interviewing. He makes two main arguments. First, design should centre on users, and the patient may be the device's main and repeated user, not the doctor. Second, building SLT for under-resourced languages costs so much that simpler tools or deliberate "cheats" are often wiser. Evidence comes from small studies:

  • a Chinese–English pipeline, where ASR was the weak link;
  • poor OCR of prescription labels;
  • a laptop/tablet tool for Somali asthma patients built on predetermined questions with recorded answers.

The tool got very high satisfaction but could not handle off-script talk. The paper's message is that user needs, not technical ambition, should guide the choice of technology.

Key points

  • Wang (2007) chained commercial Chinese ASR, Chinese–English MT and English synthesis. About 70% of ASR+MT outputs were interpreted correctly, falling to 62% with speech output, while MT alone was 97% understandable. In Somers & Sugita (2003), by contrast, Japanese ASR was reliable and MT was the weak step.
  • Interim workarounds for under-resourced languages:
    • Somali output produced with a German speech synthesizer;
    • an English ASR system coaxed into recognising a small Urdu vocabulary, which worked very well when picking among a fixed set of responses.
  • Ghobadi (2007) scanned prescription labels with a handheld scanner and got largely unusable text, because of cheap printing and curved containers.
  • The Somali asthma tool offered 69 bilingual English/Somali questions with pre-recorded human speech and symbol-based answers. Its evaluation involved 26 Somali patients alongside six clinicians, a mix of GPs and asthma nurses.
    • All 26 simulated consultations finished, and in 20 every question was answered.
    • Clinicians were least satisfied with eliciting the patient's worries (42%), building a relationship (69%) and achieving the desired outcome (65%).
    • Patients rated the tablet at 91% and the stylus at 100%, but the laptop and mousepad at only 43%.
  • Pharmacy dosage instructions are presented as a natural fit for controlled-language MT, about as complex as weather bulletins.

Interesting ideas

  • I1. Testing each stage of a pipeline separately, then in combination, shows which component actually loses the meaning, rather than giving one blended score.
  • I2. A weak recognizer becomes reliable when it only has to choose among a small set of expected responses instead of decoding open input.
  • I3. Translation quality was judged by whether a person could identify the intended meaning of an answer to a known question, not by matching surface wording.
  • I4. For predictable, narrow content such as dosage instructions, controlled language and fixed templates are safer than full open-domain translation.
  • I5. Designing for two users with very different skills at once, and adapting the interface to each user's profile, makes a tool usable in practice.

For Mova

How these ideas could serve Mova, our small open language model — its files, stages and tests:

  • I1 (learn): Mova's evaluation could score tokens, tree, frames and world separately on the same items, and report where correct answers first break, to decide which stage to repair.
  • I2 (answer): for school tests and multiple-choice QA, the reader could rank candidate answers against the world of the text rather than generating free answers, which keeps the choice explainable.
  • I3 (back): the text → graph → text compressor could be evaluated by whether regenerated text still answers the same probe questions, instead of by string overlap.
  • I4 (back): generation could switch to template-based realisation for domains with fixed patterns (measures, quantities, instructions), with free generation reserved for open text.
  • I5 (frames): dialogue frames could record each speaker's role and assumed knowledge separately, so speech acts and implicatures are interpreted per participant rather than for one generic speaker.
