# Tech Sentences
Dictation-style English sentences dense in software, DevOps, cloud, self-hosting and AI vocabulary (product names, CLI tools, acronyms, model names), read aloud by one speaker. Terms use the vendor's own casing (GitHub, PostgreSQL, kubectl). Includes long-form dictation of instructions to AI coding agents. Sentences that also code-switch into Hebrew are **not** included (since 2026-10-19); they are in [English-Hebrew-Codeswitching-Sentences](https://huggingface.co/datasets/danielrosehill/English-Hebrew-Codeswitching-Sentences).
**Website: [hebrish.app](https://hebrish.app)**: get the Hebrish keyboard for Android and the desktop apps, see the results, and find every model, dataset and demo in one place.
**This is a subset of [`danielrosehill/Read-Aloud-Voice-Sentences`](https://huggingface.co/datasets/danielrosehill/Read-Aloud-Voice-Sentences)**, the full, undifferentiated
dataset. It contains every phone recording there whose `categories` include `tech` and not `code_switch`. Rows are copied
unchanged, with the same ids, columns and train/test split, by `scripts/sync_subsets.py` in the
project repository. Do not edit this dataset directly: fix the row in the main dataset and re-sync.
The subset grows as new takes are published.
**Speaker:** Daniel Rosehill, the dataset's author, who was born in Ireland and speaks English with an **Irish accent**, and who lives in Jerusalem. Every recording is his voice.
All audio was recorded on a **OnePlus Nord 3 5G** phone using its **internal microphone**, with browser echo cancellation, noise suppression and auto gain turned off.
## Layout
```
data/train/audio/<id>.wav 16 kHz mono 16-bit PCM
data/train/metadata.jsonl
data/test/... held-out set, never trained on
```
The `test` split is **term-disjoint**: a held-out term never appears in `train`.
`load_dataset("danielrosehill/Tech-Sentences")` works directly.
## Columns
The columns are the same as in the main dataset: `text` (ground truth, punctuated and cased like
Parakeet v2 output), `text_he` (the same transcript with its Hebrew terms in Hebrew script, for
Hebrew-capable models), `categories`, `target_terms`, `prompt_source`, `prompt_origin` (manual / dataset / generated), `edited`, `duration_s`,
`environment`, `conditions`, `device`, `speaker`, `speaker_gender` and `recorded_at`. The main dataset's card describes them.
## Licence
CC-BY-4.0, with sentence-text attribution per `prompt_source` as described in the
[main dataset's licence section](https://huggingface.co/datasets/danielrosehill/Read-Aloud-Voice-Sentences#licence-and-attribution).
