By Official AppDuo editorial team · Updated

Corodomo logoCorodomo8.1/10Freemium · ≈ $6.98/mo (₫179,000/mo)ELSA Speak logoELSA Speak6.9/10Freemium · ≈ $1.61/mo (₫41,250/mo)

Quick verdict

Both use AI to score your speech, but they train it differently: Corodomo is built around shadowing real videos, while ELSA Speak is built around prepared English pronunciation drills.

Corodomo suits learners who want to imitate natural speech from video, get sentence- and word-level feedback through AI Coaching and retry weak sentences, and those learning Japanese or Chinese. Plus starts at 179,000 VND/month (≈ $6.98/month) (Vietnam price list); speaking and detailed pronunciation scoring draw on a shared AI-hour allowance.

ELSA Speak suits English learners who need sound-level and intonation correction, or IELTS/TOEIC preparation on Premium. Its yearly promotional prices are low (Pro at 495,000 VND/year (≈ $19.29/year) in Vietnam) but far below list price, and the interface is English-only.

Head-to-head

Corodomo leads on 3, ELSA Speak on 2, 5 even

FeatureCorodomoELSA Speak
Core speaking method[5],[6],[16],[18]Sentence-by-sentence shadowing on videos with bilingual subtitles, IPA or furigana. 1:1 AI Coaching assigns tasks by level and goal, then guides listening, comprehension, overlap reading, shadowing without text and a recorded submission.English pronunciation and speaking drills on a learning path with daily tasks. AI scores five areas: pronunciation, intonation, fluency, grammar and vocabulary.
→ If you want to imitate how people actually speak in real videos, Corodomo fits better; if you want a ready-made drill path with clear scores per skill area, ELSA is more direct.
Pronunciation feedback detail[6],[8],[16],[23]Scores each sentence and word; flags mispronounced or omitted words and comments on accuracy, fluency and completeness. You can play your recording beside the model and retry weak sentences.According to Voicebot.ai (2021), ELSA breaks sentences into individual sounds to pinpoint errors with near real-time feedback, using a model trained on non-native accents. Intonation is scored too.
→ Learners fixing a specific English sound or their intonation get finer-grained feedback from ELSA. AppDuo's reviews of both note there is no independent check of scoring accuracy.
AI conversation practice[2],[7],[17],[18]CoroAI runs conversations based on situations or video content, such as ordering food, workplace talk, interviews and presentations, including Japanese kaiwa. Included in Plus and drawn from the AI allowance.AI Tutor from Pro up. Premium adds the bilingual AI coach and limited Interview Coach and Meeting Coach access.
→ ELSA packages interview and meeting practice as separate tools on its higher plan; Corodomo ties conversation to situations and the video you are studying, and not only in English.
Practice material[2],[12],[18]A video library organised by topic and level (everyday life, business, IT, news), which the Corodomo team says is selected and reviewed, plus your own imported videos. Automatic subtitles on imports may need correcting.A built-in lesson library: Pro covers about 40,000 exercises, 7,000 lessons and 190 topics.
→ Corodomo suits learners who want to practise on material they care about; ELSA suits those who prefer a ready-made syllabus without choosing material themselves.
Languages taught and interface languages[1],[8],[9],[10],[11],[16]Material for English (IPA, TOEIC practice), Japanese (furigana, kaiwa, JLPT practice) and Chinese (HSK practice). Interface in 11 languages (Vietnamese, English, Japanese, Chinese, Korean, Indonesian, Spanish, French, German, Russian, Portuguese).English only, with an English-only interface.
→ Japanese or Chinese learners can only use Corodomo, and English beginners navigate more easily when the interface is available in a language they read well.
Exam preparation[10],[11],[17],[18]JLPT, HSK and TOEIC practice; HSK writing is AI-graded.IELTS/TOEIC courses are Premium-only; Pro does not include them.
→ IELTS candidates get a dedicated course on ELSA Premium. Of the two, only Corodomo has JLPT and HSK practice; for TOEIC, Corodomo has practice tests and ELSA a Premium course.

Watching already-subtitled videos, lookup, dictation, translation, quizzes and flashcards do not use AI hours.3 trial uses of ELSA AI and a 30-minute Speech Analyzer trial; dictionary and pronunciation scoring are limited.
→ Corodomo renews one AI hour every month and leaves non-AI tools unmetered; ELSA frames its free limits as trial uses and trial minutes.
Personal plan prices (Vietnam price lists)[2],[17]Plus 179,000 VND/month (≈ $6.98/month) or 1,392,000 VND/year (≈ $54.26/year) (116,000 VND/month (≈ $4.52/month)); Pro 399,000 VND/month (≈ $15.55/month) or 3,156,000 VND/year (≈ $123/year) (263,000 VND/month (≈ $10.25/month)). Lifetime: Plus 2,990,000 VND (≈ $117), Pro 5,999,000 VND (≈ $234).Promotional prices: Pro 495,000 VND/year (≈ $19.29/year) (list 1,595,000 VND (≈ $62.17), about 41,250 VND/month (≈ $1.61/month)); Premium 999,000 VND/year (≈ $38.94/year) (list 2,745,000 VND (≈ $107), about 83,250 VND/month (≈ $3.24/month)).

→ At promotional prices a year of ELSA costs clearly less than a year of Corodomo, but at list price ELSA Pro (1,595,000 VND/year (≈ $62.17/year)) costs more than Corodomo Plus (1,392,000 VND/year (≈ $54.26/year)). Corodomo's plans also include the video library and listening, reading and writing tools.
Refunds[4],[17]Web purchases are final except for duplicate charges, charges after cancellation, plans not activated within 7 days, a core paid feature down over 7 consecutive days through Corodomo's fault, or unauthorised transactions; claims within 30 days. App Store/Google Play purchases are refunded by Apple/Google.The pricing page states no refund terms and only links to a 'conversion and cancellation policy' in the footer. App Store/Google Play purchases follow the store's policy.
→ Corodomo spells out its terms but refuses refunds for changing your mind, forgetting to cancel or used AI time; with ELSA, read the separate policy before paying on the web.
Voice data handling[4],[19]The policy names its AI processors (Soniox, OpenAI, Google Gemini, Anthropic Claude) and the data each receives, describes in-app consent before AI processing and limits training use. No concrete retention period.May collect audio and video recordings and share data with service providers and researchers (pseudonymised). No retention period for recordings; the notice says internet activity, geolocation and purchase data was 'sold' or 'shared' in the past 12 months, with an email opt-out.
→ Corodomo's policy says specifically where your voice goes, while ELSA's leaves room for wider sharing. Neither states a retention period, and this compares published policies, not audits.

Choose Corodomo if…

  • Learners who want guided shadowing on real videos, with sentence- and word-level feedback and targeted retries
  • Japanese or Chinese learners practising kaiwa or preparing for JLPT or HSK
  • Learners who want listening, reading and writing practice (dictation, translation, flashcards) alongside speaking

Choose ELSA Speak if…

  • English learners who want to fix pronunciation down to individual sounds and intonation
  • People preparing for IELTS/TOEIC or English interviews and meetings (Premium)
  • Learners who want a ready-made syllabus at a low yearly cost under current promotional pricing

Two different ways to practise speaking

Corodomo starts from video. You hear each sentence with bilingual subtitles, see IPA (English) or furigana (Japanese), look up words in context and repeat after the model speaker. 1:1 AI Coaching turns these steps into short tasks matched to your level and goal: listen, read the script and translation, overlap-read, shadow without text, record and submit. CoroAI adds situational conversation. All feedback is AI-generated; there is no human teacher.

ELSA Speak takes a different route: built-in drills arranged on a learning path with daily tasks, for spoken English only. Pro covers about 40,000 exercises, 7,000 lessons and 190 topics, and AI scores five areas: pronunciation, intonation, fluency, grammar and vocabulary. AppDuo's ELSA review also notes it is not aimed at learners who need grammar from the basics or live conversation with people.

Pronunciation feedback: sounds or words

According to Voicebot.ai (2021), ELSA uses speech recognition to break sentences into individual sounds, pinpoint errors and respond almost instantly, with a model trained on non-native accents. That helps when you need to fix one specific sound or your intonation.

Corodomo scores each sentence and word, flags mispronounced or omitted words and comments on accuracy, fluency and completeness. Its difference is the retry loop: play your recording beside the model, drill weak sentences, compare submissions, and let the coach use your practice history to suggest the next step. AppDuo's reviews of both note there is no independent check of pronunciation-score accuracy, so treat the scores as guidance rather than an absolute measure.

Cost and allowances

Both publish Vietnam price lists in VND. Corodomo sells monthly or yearly: Plus at 179,000 VND/month (≈ $6.98/month) or 1,392,000 VND/year (≈ $54.26/year), Pro at 399,000 VND/month (≈ $15.55/month) or 3,156,000 VND/year (≈ $123/year), plus lifetime options. Plus includes 30 AI hours a month and Pro 100. Speaking, detailed pronunciation scoring and subtitle generation share that allowance, while watching already-subtitled videos, lookup, dictation, translation, quizzes and flashcards do not use AI hours.

ELSA's Vietnam price list (updated 2 Nov 2026) is on promotion: Pro at 495,000 VND/year (≈ $19.29/year) (list 1,595,000 VND (≈ $62.17)) and Premium at 999,000 VND/year (≈ $38.94/year) (list 2,745,000 VND (≈ $107)). At promotional prices a year of ELSA costs clearly less than a year of Corodomo Plus; at list price, Pro costs more. ELSA's prices also vary by channel: on the US App Store, paid options run from $19.99/month to $129.99/year. Check the price at checkout.

Track record, user ratings and data

ELSA launched in 2015 and reached the App Store in March 2016; in 2021 it raised a $15M Series B and reported more than 13 million users. It is rated 4.7/5 on the US App Store (114,613 ratings) and 4.6/5 on Google Play (about 1.02 million reviews). Corodomo is much newer: video-based language learning appeared on its homepage in March 2025, the iOS app arrived in November 2025 and Android in February 2026, and AI Coaching only arrived in iOS version 1.1.15 (8 Nov 2026). Its 4.9/5 on the Vietnam App Store (946 ratings) and 4.8/5 on Google Play Vietnam (531) are high but rest on far fewer ratings.

On voice data, Corodomo's policy names each AI processor and describes in-app consent; ELSA's notice allows recordings to be shared with service providers and researchers and says some categories of data were 'sold' or 'shared' in the past 12 months. Neither states a retention period for recordings.

Frequently asked questions

Which is better for fixing English pronunciation?

If your problems are individual sounds or intonation, ELSA gives finer feedback because, according to Voicebot.ai (2021), it breaks sentences down to sounds. If you want to sound like real speakers in video and retry sentence by sentence with guidance, Corodomo fits better. Neither has an independent check of scoring accuracy.

Can I use ELSA for Japanese or Chinese?

No, ELSA teaches English only. Corodomo has Japanese material (furigana, kaiwa, JLPT practice) and Chinese material (HSK practice with AI-graded writing).

Which free tier lasts longer?

Corodomo gives 1 AI hour a month, up to 3 imported videos, and leaves already-subtitled videos, lookup, dictation, quizzes and flashcards unmetered. ELSA's free tier has 3 ELSA AI trial uses and a 30-minute Speech Analyzer trial, with limited dictionary and pronunciation scoring.

Which is cheaper?

On the Vietnam price lists, ELSA Pro is on promotion at 495,000 VND/year (≈ $19.29/year), cheaper than Corodomo Plus at 1,392,000 VND/year (≈ $54.26/year); ELSA Pro's list price is 1,595,000 VND/year (≈ $62.17/year). Corodomo also sells monthly (Plus at 179,000 VND (≈ $6.98)), while ELSA's Vietnam price list has yearly, 3-month (Premium) and lifetime plans. The plans are not equivalent in features.

Is Corodomo's AI Coaching a real teacher?

No. AI Coaching assigns tasks, scores recordings and suggests next steps using AI. ELSA's feedback is automated too, and AppDuo's review notes it is not aimed at learners who want live conversation with people.
