AssemblyAI and DeepL Enable Multi-Lingual Subtitles for Videos

Subtitles
play
a
crucial
role
in
making
video
content
accessible
to
a
broader
audience.
Traditionally,
creating
subtitles
involves
painstaking
manual
transcription
and
synchronization.
However,
advancements
in
AI-driven
technologies
now
offer
more
efficient
solutions.
According
to

AssemblyAI,
a
new
method
leverages
AssemblyAI’s
transcription
capabilities
and
DeepL’s
translation
services
to
generate
multi-lingual
subtitles
swiftly
and
accurately.

Using
AssemblyAI
for
Transcription

AssemblyAI’s
audio
transcription
feature
can
transcribe
video
content
into
text
within
minutes.
This
asynchronous
transcription
service
allows
users
to
upload
a
video
file
and
receive
a
transcription
in
formats
like
SRT
or
VTT,
which
are
commonly
used
for
subtitles.

In
a
tutorial
provided
by
AssemblyAI,
users
can
build
a
web
application
in
Go
to
handle
video
uploads,
transcribe
the
audio,
and
generate
subtitles.
The
tutorial
outlines
the
setup
process,
including
creating
a
directory
for
the
project,
initializing
a
Go
module,
and
writing
the
server
code
using
the
Gin
framework
and
UUID
for
unique
job
identifiers.

Integrating
DeepL
for
Translation

Once
the
video
is
transcribed,
the
subtitles
can
be
translated
into
multiple
languages
using
DeepL.
DeepL
is
known
for
its
high-quality
translations
and
supports
various
languages,
making
it
an
ideal
tool
for
this
purpose.

The
tutorial
demonstrates
how
to
create
a
route
that
handles
the
translation
request,
sends
the
transcribed
subtitles
to
DeepL,
and
receives
the
translated
text.
This
translated
text
is
then
integrated
back
into
the
web
application,
allowing
users
to
select
their
preferred
language
for
subtitles.

Frontend
Implementation

On
the
frontend,
the
application
periodically
checks
the
transcription
status
and
updates
the
user
interface
accordingly.
Once
the
transcription
is
complete,
a
video
element
is
created,
and
the
original
subtitles
are
added.
Users
can
then
choose
a
language
from
a
dropdown
menu,
which
triggers
the
translation
process
and
updates
the
subtitles
in
the
selected
language.

The
tutorial
provides
detailed
code
snippets
for
setting
up
the
server,
handling
file
uploads,
transcribing
audio,
and
translating
subtitles.
It
also
includes
instructions
for
creating
the
frontend
components
and
integrating
them
with
the
backend.

Conclusion

By
combining
AssemblyAI
and
DeepL,
developers
can
create
a
seamless
workflow
for
generating
multi-lingual
subtitles,
significantly
improving
the
accessibility
and
user
experience
of
video
content.
This
integration
not
only
saves
time
but
also
ensures
accuracy
and
consistency
in
subtitle
generation
and
translation.
