Persian Accented English Dataset
Persian Accented English delivered to your specification. A catalog entry, not a stock listing. This page covers what is specifically hard about this pairing, and which fields your specification needs to pin down.
Why Accented English in Persian is its own problem
Persian speakers' English accent is shaped by Persian phonology: consonant cluster handling, vowel insertion, stress placement. Iranian learners in Iran also sound clearly different from Iranians abroad, so the speaker's language environment has to be annotated.
The field to pin down first: Annotate the speaker's place of residence and English acquisition environment; those two account for most of the accent variation.

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 Persian demands
Written Persian and spoken Tehrani Persian are far apart: verb endings, pronouns, and connected speech all shift in the colloquial form. Transcribing spoken recordings against the written form produces text that does not match the audio.

Questions we get about Persian Accented English Dataset
How many distinct speakers can you provide for Persian Accented English Dataset?
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 the speaker's place of residence and English acquisition environment; those two account for most of the accent variation.
Can you annotate to our own guideline instead of the default?
Yes, and for this pairing we would recommend it. Persian speakers' English accent is shaped by Persian phonology: consonant cluster handling, vowel insertion, 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 Persian Accented English Dataset 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.
