Abstract

As the accuracy of Automatic Speech Recognition (ASR) nears human-level quality, it might become feasible as an accessibility tool for people who are Deaf and Hard of Hearing (DHH) to transcribe spoken language to text. We conducted a study using in-person laboratory methodologies, to investigate requirements and preferences for new ASR-based captioning services when used in a small group meeting context. The open-ended comments reveal an interesting dynamic between: caption readability (visibility of text) and occlusion (captions blocking the video contents). Our 105 DHH participants provided valuable feedback on a variety of caption-appearance parameters (strongly preferring familiar styles such as closed captions), and in this paper we start a discussion on how ASR captioning could be visually styled to improve text readability for DHH viewers.

TL;DR

In an in-person study with 105 Deaf and Hard-of-Hearing participants, the authors surveyed preferences for how automatically generated (ASR) captions should look during small-group meetings, finding strong preferences for captions placed inside the video at the bottom, two lines of text, and Arial or Times New Roman fonts, while captioning type and appearance preferences were split. The authors recommend that developers of ASR captioning software give users extensive customization options.

Key findings

  • All five caption-appearance questions had significant chi-square goodness-of-fit results: Q1 (type) χ²=55.333, df=4, p=2.766e-11; Q2 (appearance) χ²=68.829, df=3, p=7.604e-15; Q3 (location) χ²=165.24, df=4, p<2.2e-16; Q4 (number of lines) χ²=200.53, df=6, p<2.2e-16; Q5 (font) χ²=240.67, df=10, p<2.2e-16.
  • Significantly preferred options: Q1 — Movie style (white text) and TV style (black box); Q2 — Movie subtitle style and TV CC style; Q3 — Inside the video (bottom); Q4 — 2 lines; Q5 — Arial and Times New Roman.
  • Q1 and Q2 showed participants "almost divided" between TV CC Style and Movie Subtitle Style. The strong preference for captions inside the video (bottom) contrasted with Crabb et al.'s recommendation of outside-the-frame placement, and the 2-line preference contrasted with Kushalnagar et al.'s observed preference for 3+ lines; the authors speculate this reflects the small-group live-meeting context versus online video viewing.
  • Thematic analysis of 116 open-ended comments (2069 words) surfaced themes of familiarity with specific styles (n=43), readability of captions (n=24), captions occluding video (n=21), and captions closer to speaker (n=6), revealing tension between readability and occlusion, plus a desire for customization.

Methods

  • IRB-approved in-person controlled experiment at the authors' laboratory, part of a larger project on DHH users' use of ASR tools. Participants were recruited by e-mail and campus flyers, screened as identifying as Deaf or Hard of Hearing and using captions when viewing television, and paid $40 for a 60-minute session.
  • 105 DHH participants (69 Deaf, 36 Hard-of-Hearing; 58 male, 47 female; ages 18–30, mean=22.105, median=22). Participants first viewed videos of ASR-captioned mock business meetings (average Word Error Rate 23.2%) to become familiar with ASR captioning, then answered five caption-appearance questions (Q1–Q5) presented with ASL videos, closed captions, and pictures of options, plus open-ended questions.
  • Analysis: chi-square goodness-of-fit tests for each question, and a two-round consensus coding thematic analysis of open-ended comments conducted by the authors (two of whom are DHH).

Limitations

  • Stated: the authors note they are conducting a second study with a larger pool of online participants to investigate their speculation about whether preferences differ between ASR use for small-group meetings versus online videos (e.g., YouTube); the placement and line-count differences from prior work are described as speculation.
  • Evident from the text: participants were recruited on a university campus and ranged only from 18–30 years old, so older adults and non-campus populations are not represented; the goodness-of-fit tests establish that some options were preferred over others but do not provide pairwise comparisons among the preferred options; the abstract text provided is truncated and does not report results.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
