Changelog
What's changed in Rostra, release by release. Every download link on
this site always points at the latest version.
0.1.2 — 26 August 2026
Added
- Units are read as units, not spelled out.
"15 MW", "12 µm", "10 kΩ" and thousands of other combinations
are now spoken correctly without each one having to be added by
hand — where before "kW" worked and "MW" did not. Heights and
sizes written with prime marks are read as measurements at
last — 5'11" is "five feet eleven inches" and 12" is "twelve
inches", where every other text-to-speech tool we tested reads
them as silent pauses. Coordinates come through as
coordinates, and quoted text is left alone. Throughput and
rates read the way they are meant: "35 tok/s" is tokens per
second, "72 bpm" is beats per minute, "30 psi" is pounds per
square inch, and a data rate now tells bits from bytes
correctly. Dimensions read as dimensions — "9x13" is "nine by
thirteen". Compound rates read properly too, ranges say "five
to ten kilometres" instead of running the numbers together,
blood pressure reads "one twenty over eighty millimetres of
mercury", and "1/2 cup" is "half a cup". Compass bearings stay
bearings: 95°W is west, while 60 W is watts.
Changed
- Rostra's log file no longer grows without
limit. It is now capped, keeping recent history and
discarding the oldest, so a long-running install cannot slowly
fill the disk. Reads also record more about how they went, so
a problem reported after the fact can be traced instead of
guessed at.
- The French-timbre voice is now labelled "French
(Accent)" in the Voice menu. "French" previously
appeared twice meaning two different things — a
French-sounding English voice nested under English, and the
actual French language listed separately.
Fixed
- Rostra starts in seconds again instead of stalling
with an empty menu. When the system's audio was busy,
opening the audio device could hold up startup for the better
part of a minute — during which the menu bar showed "Engine:
connecting…" and the Voice menu stayed empty. Rostra now
starts without waiting on the audio device and attaches it on
the first read.
- The app could start half-dead: empty Voice menu,
gray icon, hotkey not responding. One internal fault
at startup silently stopped every background-to-UI update in
the app while playback kept working, which made it look like
several unrelated bugs. Menus now reload their content instead
of being carried across rebuilds, and a menu that ever comes
up empty refills itself within a second.
- Rostra reads exactly what you highlighted in code
editors and chat panels. In some apps a read could
pick up far more than the selection — surrounding interface
text and whole neighbouring messages — and speak that instead.
The selection is now cross-checked before it is read, and
anything that does not match falls back to a method that
captures the highlight precisely.
- "Open at Login" now works on macOS. It was
silently never taking effect — and the option was hidden, so
there was no way to tell. Toggling it on now reliably adds
Rostra to System Settings → Login Items (macOS asks once for
permission to do so), and if anything stops that, Rostra opens
the Login Items pane and says what to click instead of failing
quietly.
- Rostra no longer freezes for half a minute and goes
silent after audio devices change. Starting a read
could stall roughly 31 seconds and then silently do nothing
when the system's audio device was asleep or mid-switch (seen
with and without Bluetooth headphones). The app now only
re-opens the audio device when the device list has actually
changed, caps how long a re-open may take, and shows "Audio
device unavailable — try again" instead of failing
silently.
0.1.1 — 13 August 2026
Added
- Rostra reads Bible scriptures the way a person
would. Turn on Scripture Preset in Additional Settings
— free tier — and verse numbers become landmarks instead of
interruptions: announced when a verse begins a sentence, passed
over silently when it lands mid-sentence, because a sentence in
scripture routinely runs across several verses. References are
spoken the way a person says them, and it works on text copied
straight from the Bible sites people actually use. Off by
default: the same "[1]" that marks a verse here marks a footnote
in an academic paper.
- The Voice menu now tells you which voice is
selected. It reads "Voice (Hazel — American English)"
rather than just "Voice", so your current choice is visible at a
glance instead of two submenus down.
- Speeds and rates are read as rates.
"9.8 m/s" is spoken as metres per second, instead of reading the
slash aloud. Prices like "$500/m" still mean per month.
Fixed
- Seven pronunciations reported from real use —
durations, rates, abbreviations, and words whose correct reading
depends on the sentence around them.
0.1.0 — 7 August 2026
Added
- Words that are spelled the same but said differently
are now read correctly. "Play the record" and
"Let me record it" no longer sound the same. Neither do
content, read, close, wind,
present, object, desert,
progress, separate, permit,
estimate and dozens more. Rostra now reads each one the
way the sentence means it. Anything genuinely ambiguous keeps the
reading it always had, so nothing that sounded right before
sounds different now.
Improved
- Rostra is faster. The engine that turns text
into speech has been rebuilt from the ground up. Reading starts
sooner, long documents finish quicker, and the app is lighter on
your machine.
- Windows: Support menu. Report a problem, share
feedback, or copy diagnostics without leaving the app — the same
options macOS already had.
- Windows: installing over a running copy now works.
Upgrades no longer fail when Rostra is already open.
0.0.17 — 5 August 2026
Fixed
- Japanese voices now read kanji correctly. They
used to mispronounce Japanese text with kanji in it — now they
read it properly, with better pacing and punctuation in both
Japanese and Chinese.
0.0.16 — 30 July 2026
Added
- Rostra now breathes like a person reading aloud.
A long sentence with no punctuation gets a small breath before
connecting words once it runs long enough that it would
otherwise play as one unbroken sprint. Questions get a beat of
air afterward so they land before the next sentence starts.
- Emphasis you can hear. Text marked bold or
italic, and emphatically capitalized words, are spoken with a
real push — a small pause plus stressed pronunciation.
- True high speeds up to 4× (Pro). A real 4×,
not a dial that quietly stalls short of it — pauses keep their
full length at every speed, so the text's structure stays
audible even at a skim.
- Trading Preset (off by default). Signal and
chart text reads the way a trader would say it — tickers,
entry prices, timeframes, and stop/target shorthand all read
naturally instead of colliding with dictionary words.
- A 55th voice — Timbre (French).
Fixed
- A batch of reading defects found in listening tests — dropped
arrows in ranges, misread abbreviations, and a few date/number
formats that read oddly.
0.0.15 — 27 July 2026
Fixed
- Rostra sometimes answered to your old shortcut as
well as the new one after changing it. Fixed —
changing your shortcut now always fully replaces the old one.
Changed
- Recording a custom shortcut is now a Pro feature. Free still
includes a working set of preset shortcuts.
0.0.14 — 27 July 2026
Added
- Custom hotkey. Set your own Speak Selection
shortcut from the menu, with live confirmation as you press it.
- Export format submenu. Export Selection as
Audio now offers WAV and MP3 as separate menu items.
Fixed
- A rare issue where starting a new read while one was still
playing could cut it off, repeat part of it, or go silent.
- The hotkey recorder capturing its own copy action while open.
- Selected text occasionally not being captured on the first
press of the shortcut.
