Indonesian Accented English Dataset
Indonesian accented english sourced to your specification — no inventory, no fixed listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why accented english in Indonesian is its own problem
Indonesian speakers' English accent features follow directly from Indonesian phonology — the voicing contrast, how word-final consonants are handled, stress placement. English education in Indonesia also varies widely, so proficiency stratification explains the data distribution better than accent stratification does.
The field to pin down first: Annotate both accent source and English proficiency level, each with stated criteria for how it was assessed.

What accented english data is
English speech from non-native speakers or specific regional accents, grouped by accent origin, used to improve accent robustness in ASR.
What buyers get wrong about it
The granularity of the accent label is what matters — "Indian accent" is too coarse; tagging down to the specific first-language background is what makes the data usable. The annotation scheme has to be settled first.
The specification field that decides the quote
Whether accents are grouped by first-language background or by geography — the two schemes are not interchangeable.
The language side: what Indonesian demands
In everyday speech, Indonesians mix in local languages (Javanese, Sundanese) and English loanwords heavily. Three language components inside a single sentence is normal, so word segmentation and annotation rules have to be fixed before collection begins.
What we can put in this delivery
-
Read and conversational speech
Scripted recording for TTS, and unscripted conversation for recognition. Specified separately because they need different speaker pools.
-
Transcription to your convention
Orthographic or phonetic, with the guideline written before production and shared with you for review.
-
Speaker metadata
Age band, gender, region and dialect background per file, so you can slice the dataset rather than take it whole.
-
Consent documentation
Signed speaker consent covering the intended use, plus collection methodology and the annotation guideline.
-
Pilot batch
A small batch first, which you can reject. Misalignments surface after a few hours rather than at delivery.
-
Delivery in your format
Audio format, sampling rate, segmentation length and metadata schema set to your pipeline's requirements.

Questions we get about Indonesian Accented English
How many distinct speakers can you provide for Indonesian Accented English?
It depends on the specification and the timeline, and we will give a real number rather than a target. For this pairing, speaker recruitment is usually the step that sets the schedule. Annotate both accent source and English proficiency level, each with stated criteria for how it was assessed.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Indonesian speakers' English accent features follow directly from Indonesian phonology — the voicing contrast, how word-final consonants are handled, stress placement. That is exactly the kind of decision a default guideline leaves open, and it is where annotators diverge. Send us your guideline, or we will draft one and you can review it before production starts.
Do you offer a sample before we commit to a full run?
Yes. Select a free sample in the request form and describe what you need. A pilot batch is the cheapest way to establish whether the quality bar is reachable for Indonesian Accented English before committing to the full volume.
Is the data licensed or owned outright?
Licensing terms are set per project, so tell us how the model will be used and whether it will be distributed. Consent documentation travels with the data either way, and we do not handle medical or clinical data or recorded telephone calls.
